The invisibility is probably due to the server not sending the player info packet to clients on the server. If the server does not send this packet players won't appear on the tab list and all players in range will ignore Incoming packets that relate to that player. This causes players to appear invisible.
@@GegaCraft well yeah what causes it is the question here beacause if its the server not sending that stuff to the clients but it does have it, why isnt it sending it? probably the high ping doing something, if it is the server not sending those packets then there isnt a reason i can find, if the client isnt sending the packets i would guess.. no i wont guess anything cos latency doesnt really change what's sent, i dont know im not a developer or mc mod or anyone that could know stuff like this greatly
8:14 for me being an active player, i actually ended up witnessing this when i was playing on windows xp (as an experiment at the time). i didnt really know that it had some associations with this op glitch, but it could of been possible that i was in this glitch state while i was afking without me even realizing it.
I recognize this. This is one of the things that was found while me and a few friends were experimenting a private server designed for testing for the Live Overflow SMP server. It’s simply an issue with the order that the join packets were sent, and I guess this can occur on bad connections sending smaller packets seconds quicker than larger ones. I don’t remember the specific order but it shouldn’t be hard to find if one were to make a mixin for the network handler.
do u have the ip to the liveoverflow smp server? Im not good with networking stuff but I have a good understanding how minecraft server works and I wanna test exploits on it XD
@@tranquil14738 packet lost, probably put on the "retry" stack, the next packet is sent successfully, the "retry" stack is attempted. That's what I think happens. Unsure if lost packets are retried though - this is a theory.
I've had similar experiences shown in this video in the past It was around 1 month ago, I was playing in my Aternos server with my friends. Then I started to lag, my packets sent to the server weren't going through, so I started to "Time out" which means I couldn't send any messages, commands break blocks, or do anything, other players would not see me moving and I would not see them moving. It's like the connection between my client and the server was broken. From the other players' perspective, I would have left the game, but in my perspective I'm still in the game because Minecraft will wait a certain amount of time before kicking me for "Timed out" This is completely normal to happen though. But the weird part is that when I am kicked and in the server list, I can't connect back to the server. And when I hover my mouse over the thing that says the ping in the server list, I see that I would still be in the server, and when I wait a while, when I can connect back to the server I think then I could have been invisible, I am not sure but that has happened to me.
@TheMisterEpic As a Java & MC Plugin developer, the reason is probably due to the PlayerMovementPacket and other PlayerDisplay packets not being sent to players. Likely an issue with protocollib. I suggest getting a packetlogger and seeing what appears in the logs as well as updating protocollib and all other plugins. If I can get packetlogs or src code of the custom plugins I can check for bugs. Not 100% sure it is a custom plugin error though. The cause is probably due to the order that the join packets were sent due to packetloss, and in a normal up to date paper server with no bugs this should not work but protocol lib is probably doing something. Not 100% but if you want to replicate it, I suggest sending the join packets in a different order via a mod.
@@chalk-consumer0 Yes. If you have a listener to listen for the order of the packets, if they are in the wrong order, stop the connection. Pretty simple.
yeah, @sirbrixalot6177 said that he and his friends had already accidentally found it while messing around with the game for a technical server, and it is indeed caused by the wrong order of packets (although I don't know, I doubt they used any plugins) their comment: *"I recognize this.

That is a worryingly dangerous bug, I hope you can find a way to fix it. It is also worrying to think if it worked on other servers, I guess as of now we have no idea. I would try to recreate the bug, but my computer isn't laggy enough, so I don't think I would be able to.
@@aidenking3557 OH Btw funny thing, I had a glitch on Rainbow Realm that's related to one of MisterEpic's older glitch videos, the one where ur kinda like on two servers at once
Sorry for the awful particles LOL! Great video! This is very interesting, oh well time to get bugtesting I guess. I really want to find out more about this and help find out how to replicate it consistently.
@@Charlsmagne not to 100% yes. But they are both related in that they both make the player invisible, and that they remove the players hitbox, and they are also both ping, and lag related.
this actually happened on the hermitcraft server, grian was just playing and other members couldn't see them, couldn't hear them from the voice chat mod, couldn't see them on the tab list
It also appears that the problem at hand is related to the order in which the join packets were transmitted. It is possible that this issue may arise when a weak network connection sends smaller packets at a faster rate than larger ones.
this kinda reminds me of a time when 2b2t players managed to create a lag machine that made people near it have there hitboxes removed. this only occured once from what I know and It couldn't be explained
@@bucket6079 I have to disagree here. I think it's exactly the same bug. The fact that both have a similar root cause (lag-related) and an identical effect (hitbox removal) is almost certainly more than coincidence.
@@pandapip1 the problem itself, yes, is similiar but the causation is entirely different here the versions are also different since 2b is on 1.12.2 and mrepics servers is on 1.19
there are some crazy glitches out there... but this... this is very intresting. I hope you can find out exactly how this happens and i also hope you're able to fix it. good luck
I was getting this glitch consistently like every other login on a vanilla server for a decently long while around 2 years ago and another time I got it constantly when joining a rather laggy Rift server on a snapshot I had made at the time for modded survival so I think it may be a Minecraft bug and not a plugin bug.
Hi Misterepic. FitMC made a video about this exact same bug. It occured on 2b2t 2 years ago. The video is titled "How 2b2t's "Immortality Machine" was Made"
I think it might be due to the connection failing during some important stage of connecting with the server or while playing. This makes sense in the connection with the lag machine on 2b2t that also gave invincibility and invisibility.
I thought of that too. It seems like the exact same glitch, since the hitbox clearly disappeared (see the player who punched through the 'godmode' player).
2:30 -- The particles are probably made like this to make it easier to spot invis players in BW/SW. I used to do the same and it does actually help to spot the players!
What this reminds me of is a bug first discovered on 2b2t which was originally just a really big lag machine but the players who made it found out that it created soo much lag that they would go invisible and would have their hitboxes removed from existence but the lag machine created so much lag they had to turn it off or they would be banned. Edit: Theirs a video on FitMc's channel ( A 2b2t Historian famous for the saying "ON the oldest anarchy server in Minecraft") covering a machine that granted players immortality and complete invisibility.
This happened to Grian in Season 8 of HermitCraft, I believe, as well as a few other people on the server. From what I remember it could be fixed server side by going through a Nether Portal.
I had a 1.8 survival server and accidentally had this happen a few times. We tried to research it yet found nothing on google similar. All we could figure out is it had something to do with chunk loading, because it always initiated on a chunk border.
Something similar actually happened to me before playing on a friend's realm. A friend went to the spawn to show me something, but when he was right in front of me I didn't see him. Similar to what you showed I couldn't damage him, but he could hit me. However this is a realm with no plugins and this glitch still occurred and I was told that he would experience that glitch sometimes on this realm. I'm not sure how it works, but I am confident that it's not the plugins thats causing the problem since it has occurred on a pure vanilla server.
Okay ToggleXYZ is legit amazing. They discover a game breaking glitch and their immediate reaction is to inform the owner, test how it works and its limits instead of abusing it, and try to figure out how it happens with the staff so that it can be fixed. Truly a chad player right there.
I had this happen a few years back, I was on a factions server and raided a base, killed them all without being hit and didn’t think anything about it until they complained about dying for no reason without seeing anyone
I may have had a similar (or the same) glitch before. I was playing on LAN with one of my friends, until my internet went out for a few seconds. When it came back, I was completely invisible, even in third person mode. I couldn't be damaged and could damage other players. It didn't go away until I restarted the game. I don't know if it's the same, but I just put the idea out there.
this bug seems familiar, this happened before on 2b2t when some players made an incredibly large lag machine, but this time, it didn't log them out, it simply made them invincible and also invisible, maybe the lag has to come from the server?
I may have experience this before without realizing it too. I couldn't do any commands and it wasn't saying "invalid command' or anything. I assumed it was lag.
I have experienced a similar bug. Basically, after a server reload, i couldnt be hit OR hit anybody. I could also fly while hitting in the air. The only way for me to hit or be hit by other players was projectiles. I wasnt invisible, but i found the similarities quite interesting. The reason for this was a bug with mobs and essentials(i used F3 + B to see the hitboxes and then logged on with wurst with truesight).
Interesting. One of my friends showed me an exploit that allowed him to die, rejoin the server and become invisible. He said that he sends the necessary packets that remove the post-death screen. He could move freely, open chests and take and put things there, as well as beat players. As soon as he wanted to get out of this state, he sent a revival package, but all the things taken after the revival disappeared. I believe that this exploit may be related to unsent packets that are associated with high ping, and if so, then the exploit may have the same roots as yours. Unfortunately (or fortunately) he didn't tell me everything about how it works.
My guess is that it isn't plug-in specific, but that it has to do with the lag spikes more. If you try to join the server during a lag spike, you might be joining the server at the exact millisecond that you "time out", which would be why you don't get listed in the server list is because the server thinks you timed out, but your client thinks you made it in, so it lets you interact with everything.
something like this could be the case probably not this exact thing, since if the client would still have to talk to the server for interactions, but the bug might be from time outs might be from lag spike joining, like you said my own guess is that somehow the server just never asks some of your player's info(lag spike maybe?), like hitbox, skin, and maybe even what to render either way, the implications of this bug are quite scary im likely wrong about this but oh well
no minecraft dosent work like that because if you get "timed out" all packets will stop being sent to and from your client you are able to see this with the use of a hack client or something of the sort (yes with the client on u will be able to move around and everything as if nothing had happend but there would be a client side thing pretty much thiking like its a massive lag spike counting the seconds that you havent received a packet
So this reminds me a LOT of something i used to do sometimes on a factions server i used to play on. I had in my custom client a mod i made called c-lock Or client lock. It would essentially halt the entire clients process. Sort of similar to the old trick of right clicking on the window bar. After about 30sec of your client not sending any packets. (or specifically the keep alive packet) the server will kick you. I found that if you locked your client. Then changed IP addresses. (easy to do in places like Australia with dynamic IPs) force kill minecraft. Then reopen and right away reconnected. A good portion of the time you would get a similar pseudo invis. It was as if the server was somehow confused about which IP you were actually on. Sending some of the packets to your original one. And some to your new one. You had to do all this within 30sec before the server registered that you timed out and kicked you, otherwise it would not work. No idea if i still have a compiled version of that mod anywhere. And it was written for 1.8 (yes i mean 1.8 from 2014) so prob couldnt connect to your server on that old a client anyway.
This is probably (emphasis on probably) due to the high ping where your game loads the world entirely and has the sets of code that loads in player data and other game codes but the internet issue makes the server think you are still in the phase of joining the world but your actual player model hasn’t loaded yet but the game itself loaded for you on your side. I don’t know if other people experience this but sometimes when my ping is sipping and I join a server like PvP Legacy I actually join the game but my player model hasn’t shown on my side, I am still testing to see if someone else’s account can see because if so I might have found this glitch aswell and this was sometime around last month. Whenever this happens and it is spiking my ping is around 250-331 ms if this is the same ping range as you this could almost defiantly be a ping issue (I have not been able to use this on a single player because that world is run on my actual pc so I get -1 ms, this is another factor on why I think this is a ping issue)
This reminds me of a bug on Hermitcraft. In season 8, Grian logged in, but was completely invisible to Mumbo Jumbo. He proceeded to tease and prank Mumbo, eventually spawning a Wither in the base they shared with a few other people.
this is a prime example of the difficulties of async coding, its most likely the protocol lib as it changes how most packets are handled, the cosmetics are seperate from the player entirely and only need to appear at a location so its unlikely that. There are tons of issues like this present my favorite is from vanilla minecraft and thats being able to convert any block into a falling block in vanilla
from the sounds of it, it's actually a vanilla bug, since people have been able to do it for a while, and on many servers it's just due to having some packets sent at the wrong order, the server forgets to send that invisible player's info to other players, so their clients ignore any data relating to it (because why would they accept data for a non-existent player, in their view) some people claim they could do it rather consistently 2 years ago, even, and others have found it more recently it's happened to people trying to exploit minecraft for a server that requires exploits to even be playable (for fun) it's happened on hermitcraft (to grian) I kinda doubt that EVERYONE was using a common plugin...although it is also very possible...but if it is a common plugin, then that protocollib may indeed be the culprit
I think this absolutely has to be lag-related. FitMC made a video a couple years ago about 2b2t players accidentally achieving this same state by using a massive lag machine, although it could not be successfully replicated
A while back ago, something similar happened at 2b2t. I’m not sure about if they became invisible, but they discovered invincibility by activating their lag machine
this type of things (similar stuff) always happens to me(not always but happens once in a while). These things dont even exists when i try to find in yt but i somehow manages it fix it. I would love to try it but i have premium mc acc :( ↓ One of the weird things happened to me was- you remember the boat glitch in 1.16? where you right click fast enough server would think you as still in boat but you can roam around, interact nearby things, ghost blocks etc. I actually managed to do this thing on 1.18 with mule.I was using the mule to about on my friend's base to get back my stuff after i died. My base was in the mountains and i has bamboo up there. i broke those, made sticks. my mule was near crafting table. when i clicked it, it didnt opened at 1st, but on 2nd click it did actually opened. i made ladders. mlg and was going there. upon shifting in water, i got tp back to mule and i had those ladders and the ladders placed on the my mlg, i was shocked with it and confused. i was remembering that how i replicated the glich but it didnt worked on 2nd time..... all i remembered was said in this message Another thing happened to me was - I actually rested/courrupted the chunks of other server. it was a moded server but i dont think that the reason was moded or vannila, according to my theory it was my PC with bad wifi or smt else but reason is my pc. so the thing was that my friends (5-7) just created the smp to play on and with the despite of using correct mods with same version, i wasnt able to join server. it was giveing me errors to join like shown in video "Internal Exception: java.net.socketException: Connection lost" it was smt tlike that. i was able to join world and everything was freezed at the same tick when i joined in my client and not theirs. it only chunk that loaded was spawn's main 1st chunk. thats it and nothing else loaded and one of my friend was in the chunk and was freezed in air(was jumping probably). and i asked them to reset the server. that didnt worked. next day when i tried to join, it gave me different error and was so odd probably random code lines. i tried to rejoin and it chunk were so odd. just look at this spawn 5x5 area thing. X=corrupted chunks, O= normal chunks. XOOOX OXOXX OXXOX XOOXO the thing is not accurate but it corrupted something like this and they probably created a new server after all There are many other things happened but these 2 were only most thing i remember well as ik i am very bad at explaining and in english so i am so sorry for that....
My friends and I found this bug on minehut a couple months ago. If we would have one client in a world and we attempted to join with another client running simultaneously, the second one that was joining would get kicked but the first one would effectively get vanished and have all the effects that you described in the video. It worked on some worlds consistently but not on others, we think it had something to do with the version the world was hosted on. It works in the lobby, one way to easily tell is that your skin reverts to an alex in your inventory
It seems to be a PlayerJoinEvent or join packets problem, sometimes if there are too many PlayerJoinEvent listeners, it may skip something some things, my best workaround on Spigot API is to have only one or two listeners on a plugin and have activation called from a separate classes. Issue Idea: There may be a certain time that on joining, too many things are happening at once not letting the server register the player. For Example: There may be the Permission Tag Generation for the TabList + Cosmetics loading + Generating Chunks and so on.... Another fix I did in a Velocity plugin to stop skipping, was to add a delay or have (in my case Velocity API) activate on a later stage of the listener, I did this to allow loading of Tablist to not be mixed up. Another Issue Idea: On the Chunk loading case, there may be multiple people joining at once and people moving to load chunks putting a bit more pressure on the server to send chunk packets which may end up skipping packets or listeners, this may cause player data to not correctly save on the server making the player kicked out, makes sense for high ping scenarios since that's usually the case due to slow data transfer/connection. Resolution Idea???? Update plugins to work together and make them not send so much at once or collect so much at once, maybe add delays, maybe even make a plugin library to allow the plugins to talk to each other for packet sending and synchronization of events. This is based on my knee-high-in-the-pool experience on plugin development, I hope it helps generate ideas and stuff. Other Ideas: Proxy to Server talking????? Proxy packets????? Proxy Effect + Server Effects Overlapping????? Proxy Packets + Server Packet interference on player data????? Mojang verification packets colliding with Proxy-Server verification packets??????
You could probably do that reliably if you have a Programm that intercepts minecrafts packets and filter the packet that announces to the server that you joined or something like that
A player sends packets to the server, the code to the server may have a bug to sending certain packets when having bad internet, thats why the invisible glitch works, it works because the missing packets aren't being send to the server.
I think this is a very specific set of events happening at the same time: 1) The player is on a poor connection (doesnt have to be switching connections) 2) The player is trying to login but the connection is so poor they have to try at least 2x to login (from timeout) 3) Once the player does load, the lag they experience logging in isnt the player experiencing lag but the server trying to load plugins while the player is actually timing out at the same time. This could be why the aesthetic plugin can load but the player model doesnt Ive tried to recreate this but somehow my connection from NZ is better than your connection shown on the video, even on my hotspot. The only thing I can suggest is to try and send a large amount of packets to yourself via cmd/terminal while attempting to login. You can set this for a variable amount of time so you can give yourself a testing window. You will have to play around with the volume of packets but of course the goal is to produce as much lag as possible on your own network that you can still login but not timing out indefinitely
Maybe it's a glitch with the connection, like when you connect, the server thinks you never joined and then you get into a 'connected but disconnected' state. Connected so you can see the server and send messages but disconnected that no one can see you or attack you. A similar glitch did happen in 2012-2013 (search it up) so maybe it's related.
I don't think its likely that it is the server not thinking you joined, being that players who join after you are glitched or relog can see you, I think its more likely that some bug causes the other clients on the server to not be alerted that you joined or something like that, but idk
The fact that you lose your skin makes me think it has something to do with offline mode, like you have already been accepted into the server but you don't ping mojang. Like how cracked servers work.
That glitch happened to Grian as well, on Hermitcraft server. He was for some reason invisible to Mumbo, and being the troll he is, he decided to troll Mumbo :D
Remember when this happened on 2b2t? Fit made a video on it and it was due to a red stone machine so idk if it is different. However, when the players got kicked from the lag they were visible again so it could be similar
I experienced something similar in a private bedrock server with my friend and I. It was probably due to connection issues, but it was basically the same. The only difference is that the “god mode” would just randomly turn on and it would be like a ghost left the player’s body, where you are playing as the ghost. No other entities move on your end, but you are still in the server. My friend killed me on his end, picked up my stuff, but I was very much alive on my end, and he was frozen in place like time had stopped alongside all other entities. Whenever I tried to break a block, he could see the breaking particles but the block wouldn’t break on his end. I wanted to experiment on the glitch more but because there was only two of us we had done basically all we could do. It is fixed though by logging back in into the server. I think these types of glitches are some kind of internet issue but the same type of ghost mode or time stop mode can happen in vanilla with no mods which is interesting. Not as broken as the glitch in this video though but thought it was relevant enough to write a comment about!
This could be potentially be a lag issue with the server. This happened on 2b2t where a lag Machine was built so powerful, their hitbox completely disappeared mid-game. Another supporting reason is that the server only uses 1 core, since that causes lag, the same 2b2t exploit occurs. My best guess is to build the powerful lag Machine in question to try to get results.
As someone who used to find pop and dupe exploits in servers back in 1.5 days my best theory would say turn the server off or restrict access to admin for a few days check for bugged chunks and ask people who have mob farms to share where they are as having multiple of em near enough are practically messing with cpu. Now I havent played in years things patch in and out but old methods get forgotten and used over again as nobody can keep up with new and old uses.
Lag machine in tb2t? There were a group of players in 2b2t who built a lag machine but caused the nearby players to become invinsible and invisible. Very similar.
This happened in 2017 on 1.10. Player could not die to the void though. Player data was corrupted by an improperly optimized script that messed with player data on login. Combined with lag this can happen. Any plugins that modify packets could be the cause, but check your player data writes. See if their is corruption.
My hypotheses: 1. You time out. And you log back in, but the "connect" packet is dropped. 2. Some plugins may only trigger a login when receiving the "connect" packet. 3. The server handles the dropped "connect" packet well on a reconnect. 4. Or maybe it's just a race condition, lmao.
This should be possible on every server, including Realms and/or vanilla servers. Try joining with a bad ping when a "can't keep up" error occurs. Especially given it happens during peak hours.
It's a network issue with vanilla minecraft. Minecraft doesn't know that you're on a server and doesn't take any instructions from the server end. The player is detectable by the server (hence why your cosmetics plugin still worked, and they could take damage from world instances , and probably hostile mobs as well.) However the client isn't telling the server that your player is online so the server doesn't send their information to other players. A simple way to solve this would be a custom plugin that will detect these variables and automatically kick the player, forcing their session to be reset. It's similar to the creative mode bug where you could join hypixel while in creative mode from singleplayer. Hypixel could detect this and alot of players were getting false banned.
I had this happen on minehut servers before, usually with 2 instances connected. Instance #1 is connected to the lobby while instance #2 is connected to the lobby, and uses /join. Instance #2 is immediately kicked back into the lobby saying "you are already logged in this server". Instance #1 however is sent to the server that instance #2 tried to join. Sometimes instance #1 is invisible on that server. This seems to happen on any minehut server, even a fabric one with no plugins. I thought this was just a minehut thing, or even a bungeecord/velocity thing, and it's very random so I didn't think too much about it.
I think this vanish glitch could be client side and not server side, because to me the detail that it can happen while you are on the server, tells me that the game tries to disconnect you, and somehow fails yet succeeds at the same time, as if something stopped the kicking process in the middle of it. Or it could be a mix of both client and server being I have seen comments mentioning player packets. These are just theories though but they make the most sense to me being the server does not give off any errors, and I feel like a player packet issue purely server side would send some sort of error into the server logs.
I might have an idea, the server itself acknowledges your connection, but pulls bad packet info it has from your original time-out because the garbage collection still hasnt taken care of it. The server dumps your bad packets eventually, and will basically forget about you reconnecting. Your client is still connected, but cant send info out because its thinks the handshake for commands hasn't happened yet. I've poked a few server operator friends to see what they say too.
This looks like the same glitch that happens in Minecraft Console Edition's Minigames, Standing in a specific spot will render you invisible and invincible, but still be able to be hurt by environmental and arrows, So I wonder if it's relates to this and helps solving what causes this bug.
I can confidently say it is ProticalLib from experience I have had on my server and another one. It seems that when the client has a bad connection to the server and "Lag's out" of the server, not all of the player's packets are unloaded, so when the player is able to reconnect, the server doesn't receive all of the packets since it thinks they are still connected and that's why when you disconnect while it's happening it will fully unload the player packets and "fix's" the problem. That is my current knowledge on this sort of issue
I believe I saw a FitMC video where some people on 2b2t accidentally created this bug when creating a huge lag machine, and they were never able to replicate it.
This is the most game breaking glitch I've seen so far. I wish I can help but my internet is stable at best on US hosted servers. The worst it can happen is lose complete connectivity to my own interne which can happen in my region due to almost constant winds.
ok so I remember the same bug but slightly different in bedrock, if you throw a enderpearl you can become invisible because your mc character is stuck in a place where said enderpearl was while your able to move around, they can still hit your character while your somewhere else, the downside is you can't pick up items and fully go vanish (Like the vanish command)
I actually encountered this bug a few times in the past. As you already discovered it has something to do with the players connection while joining. I dont think it is caused by an plugin, because it can happen on any server from what I have seen in person.
My friend got this to happen on hypixel, when he was having horrid internet problems, and downloading something at the same time. We have not tried replicating it, but he got it to work 3 times in a row by accident. We will do more testing.
Help me get to the bottom of this exploit, first person to replicate it gets $100! (instructions below)

Collab ?
This sounds similar to the god mod glitch form 2b2t I don't know if they are similar but they both made you invisible and so you can't die
Bro just Learned how to turn my Mode on
If you try to replicate this, try using a lag switch this might allow you to replicate it more easier.
The invisibility is probably due to the server not sending the player info packet to clients on the server. If the server does not send this packet players won't appear on the tab list and all players in range will ignore Incoming packets that relate to that player. This causes players to appear invisible.
soooo hypothetically it can be replicated and even forced if you just block said packets from being sent to the server
this would also explain why they can take damage from arrows and fire
@@brostrod it's not that the server isn't getting the packets, it's that the server isn't sending them to some players.
@@Howzieky so it's the server's fault for not properly handling the packet. The question is... what causes it?

Ye same
Try using your mobile data when it has ended and you will get it every single time
I recognize this. This is one of the things that was found while me and a few friends were experimenting a private server designed for testing for the Live Overflow SMP server. It’s simply an issue with the order that the join packets were sent, and I guess this can occur on bad connections sending smaller packets seconds quicker than larger ones. I don’t remember the specific order but it shouldn’t be hard to find if one were to make a mixin for the network handler.
do u have the ip to the liveoverflow smp server? Im not good with networking stuff but I have a good understanding how minecraft server works and I wanna test exploits on it XD
I remember this as well. Had a the same problem. It's hilarious (in a small server.)
Do you have the proxy ip ?
@@tranquil14738 packet lost, probably put on the "retry" stack, the next packet is sent successfully, the "retry" stack is attempted.
That's what I think happens. Unsure if lost packets are retried though - this is a theory.
I know the Live Overflow SMP
It's really technical stuff..
This sounds ridiculously powerful, hopefully there's some way of figuring out what causes it and a way to fix it soon
id give it a week haha
It seems similar to the portal god mode hack that was present a couple years ago
Fix it? Why would you? I wanna abuse the hell out of this exploit.
Devs pls fix
I've had similar experiences shown in this video in the past
It was around 1 month ago, I was playing in my Aternos server with my friends.
Then I started to lag, my packets sent to the server weren't going through, so I started to "Time out" which means I couldn't send any messages, commands break blocks, or do anything, other players would not see me moving and I would not see them moving. It's like the connection between my client and the server was broken. From the other players' perspective, I would have left the game, but in my perspective I'm still in the game because Minecraft will wait a certain amount of time before kicking me for "Timed out" This is completely normal to happen though.
But the weird part is that when I am kicked and in the server list, I can't connect back to the server. And when I hover my mouse over the thing that says the ping in the server list, I see that I would still be in the server, and when I wait a while, when I can connect back to the server I think then I could have been invisible, I am not sure but that has happened to me.
@TheMisterEpic As a Java & MC Plugin developer, the reason is probably due to the PlayerMovementPacket and other PlayerDisplay packets not being sent to players. Likely an issue with protocollib. I suggest getting a packetlogger and seeing what appears in the logs as well as updating protocollib and all other plugins. If I can get packetlogs or src code of the custom plugins I can check for bugs. Not 100% sure it is a custom plugin error though. The cause is probably due to the order that the join packets were sent due to packetloss, and in a normal up to date paper server with no bugs this should not work but protocol lib is probably doing something. Not 100% but if you want to replicate it, I suggest sending the join packets in a different order via a mod.
if this is true then would it be possible to develop an anticheat to counter this?
@@chalk-consumer0 Yes. If you have a listener to listen for the order of the packets, if they are in the wrong order, stop the connection. Pretty simple.
yeah, @sirbrixalot6177 said that he and his friends had already accidentally found it while messing around with the game for a technical server, and it is indeed caused by the wrong order of packets (although I don't know, I doubt they used any plugins)
their comment: *"I recognize this. This is one of the things that was found while me and a few friends were experimenting a private server designed for testing for the Live Overflow SMP server.

That is a worryingly dangerous bug, I hope you can find a way to fix it. It is also worrying to think if it worked on other servers, I guess as of now we have no idea. I would try to recreate the bug, but my computer isn't laggy enough, so I don't think I would be able to.

this actually happened on the hermitcraft server, grian was just playing and other members couldn't see them, couldn't hear them from the voice chat mod, couldn't see them on the tab list
It also appears that the problem at hand is related to the order in which the join packets were transmitted. It is possible that this issue may arise when a weak network connection sends smaller packets at a faster rate than larger ones.
i like when you do updates about your server, makes it feel alive.
this kinda reminds me of a time when 2b2t players managed to create a lag machine that made people near it have there hitboxes removed. this only occured once from what I know and It couldn't be explained

bro watched a Fit video and is now an expert
@@bucket6079 I have to disagree here. I think it's exactly the same bug. The fact that both have a similar root cause (lag-related) and an identical effect (hitbox removal) is almost certainly more than coincidence.

That is such a weird and rare glitch and it makes you so OP. Hopefully we'll find out what's the glitch and it won't happen again!
“I need to get to the bottom of this before powerful players abuse it” Uploads a tutorial to RUclips. Nice.
I was getting this glitch consistently like every other login on a vanilla server for a decently long while around 2 years ago and another time I got it constantly when joining a rather laggy Rift server on a snapshot I had made at the time for modded survival so I think it may be a Minecraft bug and not a plugin bug.
Hi Misterepic. FitMC made a video about this exact same bug. It occured on 2b2t 2 years ago. The video is titled "How 2b2t's "Immortality Machine" was Made"
This is just tick tock clock all over again....
E
I think it might be due to the connection failing during some important stage of connecting with the server or while playing. This makes sense in the connection with the lag machine on 2b2t that also gave invincibility and invisibility.
I thought of that too. It seems like the exact same glitch, since the hitbox clearly disappeared (see the player who punched through the 'godmode' player).
I had notices a similar glitch in 1.18 server (Java) where I would go invisible . But I wasn't immune to damage (probably) .
2:30 -- The particles are probably made like this to make it easier to spot invis players in BW/SW. I used to do the same and it does actually help to spot the players!
What this reminds me of is a bug first discovered on 2b2t which was originally just a really big lag machine but the players who made it found out that it created soo much lag that they would go invisible and would have their hitboxes removed from existence but the lag machine created so much lag they had to turn it off or they would be banned.
Edit: Theirs a video on FitMc's channel ( A 2b2t Historian famous for the saying "ON the oldest anarchy server in Minecraft") covering a machine that granted players immortality and complete invisibility.
This happened to Grian in Season 8 of HermitCraft, I believe, as well as a few other people on the server. From what I remember it could be fixed server side by going through a Nether Portal.
+1 this is the first thing I thought of upon watching the video
I had a 1.8 survival server and accidentally had this happen a few times. We tried to research it yet found nothing on google similar. All we could figure out is it had something to do with chunk loading, because it always initiated on a chunk border.
Something similar actually happened to me before playing on a friend's realm. A friend went to the spawn to show me something, but when he was right in front of me I didn't see him. Similar to what you showed I couldn't damage him, but he could hit me. However this is a realm with no plugins and this glitch still occurred and I was told that he would experience that glitch sometimes on this realm. I'm not sure how it works, but I am confident that it's not the plugins thats causing the problem since it has occurred on a pure vanilla server.
Okay ToggleXYZ is legit amazing. They discover a game breaking glitch and their immediate reaction is to inform the owner, test how it works and its limits instead of abusing it, and try to figure out how it happens with the staff so that it can be fixed. Truly a chad player right there.
I had this happen a few years back, I was on a factions server and raided a base, killed them all without being hit and didn’t think anything about it until they complained about dying for no reason without seeing anyone
I love how Australia was partly the cause for an unexplainable glitch
There's always more bugs to find that can see and take advantage of
I may have had a similar (or the same) glitch before. I was playing on LAN with one of my friends, until my internet went out for a few seconds. When it came back, I was completely invisible, even in third person mode. I couldn't be damaged and could damage other players. It didn't go away until I restarted the game. I don't know if it's the same, but I just put the idea out there.
LAN=Local Acces Network, What does your internet have to do with this?
@@robert.slatt.original he meant open to LAN which is a singeplayer option that makes your server visible to others connected to your network
this bug seems familiar, this happened before on 2b2t when some players made an incredibly large lag machine, but this time, it didn't log them out, it simply made them invincible and also invisible, maybe the lag has to come from the server?
That weird arrow falling animation happens on mcci sky battle sometimes, hopefully it doesn't cause issues like it did for u
I may have experience this before without realizing it too. I couldn't do any commands and it wasn't saying "invalid command' or anything. I assumed it was lag.
I have experienced a similar bug. Basically, after a server reload, i couldnt be hit OR hit anybody. I could also fly while hitting in the air. The only way for me to hit or be hit by other players was projectiles. I wasnt invisible, but i found the similarities quite interesting. The reason for this was a bug with mobs and essentials(i used F3 + B to see the hitboxes and then logged on with wurst with truesight).
Interesting. One of my friends showed me an exploit that allowed him to die, rejoin the server and become invisible. He said that he sends the necessary packets that remove the post-death screen. He could move freely, open chests and take and put things there, as well as beat players. As soon as he wanted to get out of this state, he sent a revival package, but all the things taken after the revival disappeared.
I believe that this exploit may be related to unsent packets that are associated with high ping, and if so, then the exploit may have the same roots as yours. Unfortunately (or fortunately) he didn't tell me everything about how it works.
@TheRentes Yes.
This right here folks, this is it.
My guess is that it isn't plug-in specific, but that it has to do with the lag spikes more. If you try to join the server during a lag spike, you might be joining the server at the exact millisecond that you "time out", which would be why you don't get listed in the server list is because the server thinks you timed out, but your client thinks you made it in, so it lets you interact with everything.
something like this could be the case
probably not this exact thing, since if the client would still have to talk to the server for interactions, but the bug might be from time outs might be from lag spike joining, like you said
my own guess is that somehow the server just never asks some of your player's info(lag spike maybe?), like hitbox, skin, and maybe even what to render
either way, the implications of this bug are quite scary
im likely wrong about this but oh well
no minecraft dosent work like that because if you get "timed out" all packets will stop being sent to and from your client you are able to see this with the use of a hack client or something of the sort (yes with the client on u will be able to move around and everything as if nothing had happend but there would be a client side thing pretty much thiking like its a massive lag spike counting the seconds that you havent received a packet
I think so too. I’ve seen this often on one server I play on.
4:04 it's a me, a squeaky
So this reminds me a LOT of something i used to do sometimes on a factions server i used to play on. I had in my custom client a mod i made called c-lock Or client lock. It would essentially halt the entire clients process. Sort of similar to the old trick of right clicking on the window bar. After about 30sec of your client not sending any packets. (or specifically the keep alive packet) the server will kick you.
I found that if you locked your client. Then changed IP addresses. (easy to do in places like Australia with dynamic IPs) force kill minecraft. Then reopen and right away reconnected. A good portion of the time you would get a similar pseudo invis. It was as if the server was somehow confused about which IP you were actually on. Sending some of the packets to your original one. And some to your new one. You had to do all this within 30sec before the server registered that you timed out and kicked you, otherwise it would not work.
No idea if i still have a compiled version of that mod anywhere. And it was written for 1.8 (yes i mean 1.8 from 2014) so prob couldnt connect to your server on that old a client anyway.
Mind adding me on discord? Id like to make a video on this.
This is probably (emphasis on probably) due to the high ping where your game loads the world entirely and has the sets of code that loads in player data and other game codes but the internet issue makes the server think you are still in the phase of joining the world but your actual player model hasn’t loaded yet but the game itself loaded for you on your side. I don’t know if other people experience this but sometimes when my ping is sipping and I join a server like PvP Legacy I actually join the game but my player model hasn’t shown on my side, I am still testing to see if someone else’s account can see because if so I might have found this glitch aswell and this was sometime around last month. Whenever this happens and it is spiking my ping is around 250-331 ms if this is the same ping range as you this could almost defiantly be a ping issue (I have not been able to use this on a single player because that world is run on my actual pc so I get -1 ms, this is another factor on why I think this is a ping issue)
I love how unique your videos are! Keep up the great work, man. You are the reason Minecraft content creation is so good. ❤️

This reminds me of a bug on Hermitcraft. In season 8, Grian logged in, but was completely invisible to Mumbo Jumbo. He proceeded to tease and prank Mumbo, eventually spawning a Wither in the base they shared with a few other people.
I’m glad you’re exposing the glitch, I’ve been using it for years and whilst I do love it, I think it’s only fair the people now know.
how does it work?
Go get the 100$ smh if you know it
@@narinatanuj8402 I don’t do what I do for money, I do what I do to send a message.
this is a prime example of the difficulties of async coding, its most likely the protocol lib as it changes how most packets are handled, the cosmetics are seperate from the player entirely and only need to appear at a location so its unlikely that. There are tons of issues like this present my favorite is from vanilla minecraft and thats being able to convert any block into a falling block in vanilla
Good thing he reported it instead of abusing it lmao
Very true
Also isn't it a bad idea to tell basically everyone on your server how to do this bug?
from the sounds of it, it's actually a vanilla bug, since people have been able to do it for a while, and on many servers
it's just due to having some packets sent at the wrong order, the server forgets to send that invisible player's info to other players, so their clients ignore any data relating to it (because why would they accept data for a non-existent player, in their view)
some people claim they could do it rather consistently 2 years ago, even, and others have found it more recently
it's happened to people trying to exploit minecraft for a server that requires exploits to even be playable (for fun)
it's happened on hermitcraft (to grian)
I kinda doubt that EVERYONE was using a common plugin...although it is also very possible...but if it is a common plugin, then that protocollib may indeed be the culprit
I think this absolutely has to be lag-related. FitMC made a video a couple years ago about 2b2t players accidentally achieving this same state by using a massive lag machine, although it could not be successfully replicated
i swear bro themisterepic has the weirdest things happen on his minecraft server specifically
A while back ago, something similar happened at 2b2t. I’m not sure about if they became invisible, but they discovered invincibility by activating their lag machine
last i remember, the lag machine deleted their hitboxes and somehow made them completely invisible
Another banger documentary from the one and only TheMisterEpic!!!!
this type of things (similar stuff) always happens to me(not always but happens once in a while). These things dont even exists when i try to find in yt but i somehow manages it fix it.
I would love to try it but i have premium mc acc :(
↓
One of the weird things happened to me was- you remember the boat glitch in 1.16? where you right click fast enough server would think you as still in boat but you can roam around, interact nearby things, ghost blocks etc.
I actually managed to do this thing on 1.18 with mule.I was using the mule to about on my friend's base to get back my stuff after i died. My base was in the mountains and i has bamboo up there. i broke those, made sticks. my mule was near crafting table. when i clicked it, it didnt opened at 1st, but on 2nd click it did actually opened. i made ladders. mlg and was going there. upon shifting in water, i got tp back to mule and i had those ladders and the ladders placed on the my mlg, i was shocked with it and confused. i was remembering that how i replicated the glich but it didnt worked on 2nd time..... all i remembered was said in this message
Another thing happened to me was - I actually rested/courrupted the chunks of other server. it was a moded server but i dont think that the reason was moded or vannila, according to my theory it was my PC with bad wifi or smt else but reason is my pc. so the thing was that my friends (5-7) just created the smp to play on and with the despite of using correct mods with same version, i wasnt able to join server. it was giveing me errors to join like shown in video "Internal Exception: java.net.socketException: Connection lost" it was smt tlike that. i was able to join world and everything was freezed at the same tick when i joined in my client and not theirs. it only chunk that loaded was spawn's main 1st chunk. thats it and nothing else loaded and one of my friend was in the chunk and was freezed in air(was jumping probably). and i asked them to reset the server. that didnt worked. next day when i tried to join, it gave me different error and was so odd probably random code lines. i tried to rejoin and it chunk were so odd. just look at this spawn 5x5 area thing. X=corrupted chunks, O= normal chunks.
XOOOX
OXOXX
OXXOX
XOOXO
the thing is not accurate but it corrupted something like this and they probably created a new server after all
There are many other things happened but these 2 were only most thing i remember well
as ik i am very bad at explaining and in english so i am so sorry for that....
i actually experienced this once on fallentech. my internet was rlly shitty at the time and the server was lagging a bit. that's prob what caused it.
Ofcoarse this is from the war criminal filled 2b2t.
My friends and I found this bug on minehut a couple months ago. If we would have one client in a world and we attempted to join with another client running simultaneously, the second one that was joining would get kicked but the first one would effectively get vanished and have all the effects that you described in the video. It worked on some worlds consistently but not on others, we think it had something to do with the version the world was hosted on. It works in the lobby, one way to easily tell is that your skin reverts to an alex in your inventory
Just tried this on og-network, does not work unfortunately
It seems to be a PlayerJoinEvent or join packets problem, sometimes if there are too many PlayerJoinEvent listeners, it may skip something some things, my best workaround on Spigot API is to have only one or two listeners on a plugin and have activation called from a separate classes.
Issue Idea: There may be a certain time that on joining, too many things are happening at once not letting the server register the player. For Example: There may be the Permission Tag Generation for the TabList + Cosmetics loading + Generating Chunks and so on....
Another fix I did in a Velocity plugin to stop skipping, was to add a delay or have (in my case Velocity API) activate on a later stage of the listener, I did this to allow loading of Tablist to not be mixed up.
Another Issue Idea: On the Chunk loading case, there may be multiple people joining at once and people moving to load chunks putting a bit more pressure on the server to send chunk packets which may end up skipping packets or listeners, this may cause player data to not correctly save on the server making the player kicked out, makes sense for high ping scenarios since that's usually the case due to slow data transfer/connection.
Resolution Idea???? Update plugins to work together and make them not send so much at once or collect so much at once, maybe add delays, maybe even make a plugin library to allow the plugins to talk to each other for packet sending and synchronization of events.
This is based on my knee-high-in-the-pool experience on plugin development, I hope it helps generate ideas and stuff.
Other Ideas: Proxy to Server talking????? Proxy packets????? Proxy Effect + Server Effects Overlapping????? Proxy Packets + Server Packet interference on player data????? Mojang verification packets colliding with Proxy-Server verification packets??????
You could probably do that reliably if you have a Programm that intercepts minecrafts packets and filter the packet that announces to the server that you joined or something like that
There have been so many of these server bugs recently
A player sends packets to the server, the code to the server may have a bug to sending certain packets when having bad internet, thats why the invisible glitch works, it works because the missing packets aren't being send to the server.
I think this is a very specific set of events happening at the same time:
1) The player is on a poor connection (doesnt have to be switching connections)
2) The player is trying to login but the connection is so poor they have to try at least 2x to login (from timeout)
3) Once the player does load, the lag they experience logging in isnt the player experiencing lag but the server trying to load plugins while the player is actually timing out at the same time. This could be why the aesthetic plugin can load but the player model doesnt
Ive tried to recreate this but somehow my connection from NZ is better than your connection shown on the video, even on my hotspot.
The only thing I can suggest is to try and send a large amount of packets to yourself via cmd/terminal while attempting to login. You can set this for a variable amount of time so you can give yourself a testing window. You will have to play around with the volume of packets but of course the goal is to produce as much lag as possible on your own network that you can still login but not timing out indefinitely
you have to admit its nice that that guy told you whether or not he was trying to flex or if he was reporting a bug
This happened on 2b2t once too, it’s a very rare bug.
Maybe it's a glitch with the connection, like when you connect, the server thinks you never joined and then you get into a 'connected but disconnected' state. Connected so you can see the server and send messages but disconnected that no one can see you or attack you. A similar glitch did happen in 2012-2013 (search it up) so maybe it's related.
I don't think its likely that it is the server not thinking you joined, being that players who join after you are glitched or relog can see you, I think its more likely that some bug causes the other clients on the server to not be alerted that you joined or something like that, but idk
The fact that you lose your skin makes me think it has something to do with offline mode, like you have already been accepted into the server but you don't ping mojang. Like how cracked servers work.
That glitch happened to Grian as well, on Hermitcraft server. He was for some reason invisible to Mumbo, and being the troll he is, he decided to troll Mumbo :D
Looks like the firework prices are gonna increase in the market 💀
0:04 I was in the video as HalfMasked13 or you just see Half best server ever
Remember when this happened on 2b2t? Fit made a video on it and it was due to a red stone machine so idk if it is different. However, when the players got kicked from the lag they were visible again so it could be similar
I experienced something similar in a private bedrock server with my friend and I. It was probably due to connection issues, but it was basically the same. The only difference is that the “god mode” would just randomly turn on and it would be like a ghost left the player’s body, where you are playing as the ghost. No other entities move on your end, but you are still in the server. My friend killed me on his end, picked up my stuff, but I was very much alive on my end, and he was frozen in place like time had stopped alongside all other entities. Whenever I tried to break a block, he could see the breaking particles but the block wouldn’t break on his end. I wanted to experiment on the glitch more but because there was only two of us we had done basically all we could do. It is fixed though by logging back in into the server. I think these types of glitches are some kind of internet issue but the same type of ghost mode or time stop mode can happen in vanilla with no mods which is interesting. Not as broken as the glitch in this video though but thought it was relevant enough to write a comment about!
This could be potentially be a lag issue with the server.
This happened on 2b2t where a lag Machine was built so powerful, their hitbox completely disappeared mid-game.
Another supporting reason is that the server only uses 1 core, since that causes lag, the same 2b2t exploit occurs.
My best guess is to build the powerful lag Machine in question to try to get results.
As someone who used to find pop and dupe exploits in servers back in 1.5 days my best theory would say turn the server off or restrict access to admin for a few days check for bugged chunks and ask people who have mob farms to share where they are as having multiple of em near enough are practically messing with cpu. Now I havent played in years things patch in and out but old methods get forgotten and used over again as nobody can keep up with new and old uses.
Lag machine in tb2t? There were a group of players in 2b2t who built a lag machine but caused the nearby players to become invinsible and invisible. Very similar.
I will try the bug on a private server with limited specs with the plugins you mentioned. We'll see how it goes
This happened in 2017 on 1.10. Player could not die to the void though. Player data was corrupted by an improperly optimized script that messed with player data on login. Combined with lag this can happen. Any plugins that modify packets could be the cause, but check your player data writes. See if their is corruption.
My hypotheses:
1. You time out. And you log back in, but the "connect" packet is dropped.
2. Some plugins may only trigger a login when receiving the "connect" packet.
3. The server handles the dropped "connect" packet well on a reconnect.
4. Or maybe it's just a race condition, lmao.
This should be possible on every server, including Realms and/or vanilla servers.
Try joining with a bad ping when a "can't keep up" error occurs.
Especially given it happens during peak hours.
It's a network issue with vanilla minecraft.
Minecraft doesn't know that you're on a server and doesn't take any instructions from the server end.
The player is detectable by the server (hence why your cosmetics plugin still worked, and they could take damage from world instances , and probably hostile mobs as well.)
However the client isn't telling the server that your player is online so the server doesn't send their information to other players.
A simple way to solve this would be a custom plugin that will detect these variables and automatically kick the player, forcing their session to be reset.
It's similar to the creative mode bug where you could join hypixel while in creative mode from singleplayer.
Hypixel could detect this and alot of players were getting false banned.
Cosmic Prisons also has an issue like this where some players will be invisible, but you can still see them because of the displayed health bar
6:40 the power of bad internet should not be underestimated
2b2t players boutta have a blast with this one if they can replicate it consistently there.
Imagine how OP this would be on 2b2t… completely invisible with hundreds of thousands of hours worth of builds at stake…
i have the sudden urge to strangle you
@@feedyjk7573 i love you too
This exact thing happened to me the other day actually. I was using a boat on a wide ocean.
I had this happen on minehut servers before, usually with 2 instances connected. Instance #1 is connected to the lobby while instance #2 is connected to the lobby, and uses /join. Instance #2 is immediately kicked back into the lobby saying "you are already logged in this server". Instance #1 however is sent to the server that instance #2 tried to join. Sometimes instance #1 is invisible on that server. This seems to happen on any minehut server, even a fabric one with no plugins. I thought this was just a minehut thing, or even a bungeecord/velocity thing, and it's very random so I didn't think too much about it.
Also, if the server is empty except for you, the tablist is just a very thin line 😆
One Exploit to rule them all, One Player to find them, One Exploit to bring them all, and in the darkness bind them
I think this vanish glitch could be client side and not server side, because to me the detail that it can happen while you are on the server, tells me that the game tries to disconnect you, and somehow fails yet succeeds at the same time, as if something stopped the kicking process in the middle of it. Or it could be a mix of both client and server being I have seen comments mentioning player packets. These are just theories though but they make the most sense to me being the server does not give off any errors, and I feel like a player packet issue purely server side would send some sort of error into the server logs.
I might have an idea, the server itself acknowledges your connection, but pulls bad packet info it has from your original time-out because the garbage collection still hasnt taken care of it. The server dumps your bad packets eventually, and will basically forget about you reconnecting. Your client is still connected, but cant send info out because its thinks the handshake for commands hasn't happened yet.
I've poked a few server operator friends to see what they say too.
This looks like the same glitch that happens in Minecraft Console Edition's Minigames, Standing in a specific spot will render you invisible and invincible, but still be able to be hurt by environmental and arrows, So I wonder if it's relates to this and helps solving what causes this bug.
I can confidently say it is ProticalLib from experience I have had on my server and another one. It seems that when the client has a bad connection to the server and "Lag's out" of the server, not all of the player's packets are unloaded, so when the player is able to reconnect, the server doesn't receive all of the packets since it thinks they are still connected and that's why when you disconnect while it's happening it will fully unload the player packets and "fix's" the problem. That is my current knowledge on this sort of issue
I believe I saw a FitMC video where some people on 2b2t accidentally created this bug when creating a huge lag machine, and they were never able to replicate it.
I'm pretty sure this has happened once or twice on hermitcraft as well
This is the most game breaking glitch I've seen so far. I wish I can help but my internet is stable at best on US hosted servers. The worst it can happen is lose complete connectivity to my own interne which can happen in my region due to almost constant winds.
The relief I got with it not being the same glitch that fit covered awhile back 😅
That was one roundabout way to advertise your server 🤣 and it worked. I watched the whole video, and want to join the server, bravo hahaha
This bug seems awfully similar to the 2b2t Immortality machine which FitMC even did a video on
This has happened to me before, probably because the server I was playing on was running on a crusty laptop.
Finally I'm not the only 1 that play from Australia
maybe it thinks it kicked you out, but your still in the server.
7:55 what if someone gained access to your minecraft account, you dont have any like lock to only be accessed from ur ip?
ok so I remember the same bug but slightly different in bedrock, if you throw a enderpearl you can become invisible because your mc character is stuck in a place where said enderpearl was while your able to move around, they can still hit your character while your somewhere else, the downside is you can't pick up items and fully go vanish (Like the vanish command)
I actually encountered this bug a few times in the past. As you already discovered it has something to do with the players connection while joining. I dont think it is caused by an plugin, because it can happen on any server from what I have seen in person.
My friend got this to happen on hypixel, when he was having horrid internet problems, and downloading something at the same time. We have not tried replicating it, but he got it to work 3 times in a row by accident. We will do more testing.
