Very cool
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?
@@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.
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.
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.
Hey its you! Didnt expect to find you here lol
@@aidenking3557 AIDENKING?? XD wow me either
@@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
@@taublix315 imma use on hive server 😆
@@taublix315 can we get on tmr?
@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?
@@catwell-white 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.

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
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.
Yo thank u for the awesome content u made for us
This bug can be similar to the imortal bug in 2b2t many years ago, which was caused by a lag machine.
@@thearchive6837 i know this sounds bad but i hope there will be chaos with this glitch on big servers 🍿🍿
Nt rlly it happens whe n players have high ping i have replicated it continuously
@@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.
@@mariopluto6721 how does arrow work then lil man
@@Charlsmagne i dont know, from a developer standpoint this seems like more than just a cooincidance, i cant explain exactly how they work.
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.
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!
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
i don't think this case is the same but I can definitely see how it looks similiar
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.
@@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
@@bucket6079 Considering the bug, to my knowledge, hasn't been reported, there's no reason why it wouldn't work in multiple versions many years apart.
This sort of sounds like the Godmode exploit that happened on 2b2t a while back. No idea what was done to patch it though, just thought I'd mention it.
That was actually my first thought too lol! I dont think it ever was patched, they just couldnt recreate it. They did use a very powerful lag machine though, so maybe someone could try to recreate that with the plugins on this server and such? And maybe they could combine that lag machine with low ping and that might be enough to consistently do so. Honestly too much work for me to bother with lol, but ya never know, could be worth pursuing.
This needs more mentoning, this is almost the same glitch
@@jaroIG It honestly might _be_ the same glitch, just using 1.18 plugins instead.
(I hope MisterEpic finds this comment)
@@optionapoop given it seems purposely bad connection is required for this one, it could very well be the same exploit. Rather than using a bad connection, they simply used a lag machine to replicate the same thing.
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
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 like when you do updates about your server, makes it feel alive.
I had notices a similar glitch in 1.18 server (Java) where I would go invisible . But I wasn't immune to damage (probably) .
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.
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!
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.
I love how Australia was partly the cause for an unexplainable glitch
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.
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.
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.
That weird arrow falling animation happens on mcci sky battle sometimes, hopefully it doesn't cause issues like it did for u
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).
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
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
What I think is going on is when you join the server your computer and the server have to communicate sending packets to each other, and what could be happening is that part of the packet somehow gets lost and doesn't make it so the server has to make up for any lost data thus putting you in that semi-invincible state.
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.
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 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
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?
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 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?
This is just tick tock clock all over again....

I love how unique your videos are! Keep up the great work, man. You are the reason Minecraft content creation is so good. ❤️
yes
I need a Collab with him
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
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.
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
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
i swear bro themisterepic has the weirdest things happen on his minecraft server specifically
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.
There's always more bugs to find that can see and take advantage of
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
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
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.
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!
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.
Another banger documentary from the one and only TheMisterEpic!!!!
imagine when the first person to figure this out just decides to be a villian and exploits it
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.
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
Sounds like the server has lost track of your Player class instance in some regard. Especially the command behavior shows signs of this. As you mentioned, it’s entirely possible that this is the result of a plugin incorrectly handling the Player instance asynchronously. Although unlikely, the invisibility could be the result of a plugin/the server sending an EntityRemove packet to the other clients for whatever reason. The internet change issues lead me to think that there might also be an issue with the handling of the KeepAlive packets, possibly resulting in the aforementioned behavior.
These are just a few hypothesis based on my prior knowledge, hopefully they help in some way.
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 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 😆
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.
congrats on 500k!!!!
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
I will try the bug on a private server with limited specs with the plugins you mentioned. We'll see how it goes
I'm curious if the client logs would show anything of use.
Also, didn't realise you were an Aussie too. 240ms seems about right for us on US servers lol.
Since you can't use commands while in this vanish mode, maybe make players require to type a certain command to be able to play on the server? Like to enable pvp or something
I've had a couple of weird bugs like this happen on Bedrock Edition. Friends of mine would join the Hive server and I could see them, but they couldn't see me or vis versa. a truly bewildering experience happened on my realm, where me and my friend would just disappear without a logout message in chat and we would both break a block and neither of us could see it, like we were on two different copies of the same world, we both relogged and I don't remember if the blocks went away or not. everything was too smooth to be the lag, even for my friend on the switch.
Amazing video! Keep up the great work!
i love these videos so much, its so mysterious while actually being real
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.
I've seen a similar glitch years ago on Minecade's Super Craft Bros. when it was still around, however I think players affected by it were simply invisible and completely invincible (not sure if I ever saw projectiles hit them) and didn't have any of these extra details. I think it occurred only after they died and respawned, and it seemed to only happen if you had Forge installed; players without Forge could still hurt them, I guess. I guess it really was just due to Forge, since I believe I saw a bug report about it during the time. I don't think I've ever encountered the glitch in your video, however.
There may have been another glitch unrelated to Forge, since I remember players spawning invincible with no items, though they weren't invisible.
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.
This looks exactly like what started happening on the Hermitcraft server nead the end of Season 8 (most notably look at the Grian and Mumbo video where an invisible Grian attempts to gaslight Mumbo into spawning a wither). If you haven't already, you should see if Xisuma documented anything about the issue.
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.
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.
This is a general minecraft bug that I used to experience a ton when I had an inconsistent Internet connection, basically you're half connected to a server and you sometimes get some error messages on chat when you join best examples being "unable to locate sign at (coordinates).
Personally I remember doing this bug on Hypixel Wynncraft and Manacube primarily with each of them having a different result. On Manacube I got fully trapped inside the hub unable to interact with anything, on Wynncraft I made it to the character selection screen but couldn't do anything after that, and on Hypixel I would move for like 1 to 2 seconds and then get limboed and be trapped in there. I've never really had the chance to use this bug in any practical sense but I know with some sort of way to alter the packets sent to a server through ping or even worse hacked clients this should be 100% replicatable.
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.
I have noticed the exact same thing on minehut and the servers on it where I will occasionally become invincible and still be able to hit others and be seen but not be but it take any damage, but I still show up on the tab list which is weird and as well, my pig is usually only around 40-60 but I have 2 wifi's and have noticed when I switch them my game it will d this glitch.
Bro that's an old ass pig
This exact thing happened to me the other day actually. I was using a boat on a wide ocean.
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.
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
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.
“I need to get to the bottom of this before powerful players abuse it” Uploads a tutorial to RUclips. Nice.
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 happened to me before but not on your server. back when i didn't have a mc acc, i used to play alot on cracked servers, one of them had an exact copy of hypixel's skywars.
Rarely when i use my mob spawn egg they would attack me and push me into the void causing me to become a spectator and vanish (like its supposed to do) but then if i leave the match or join a new one i'd stay vanished until i either die again or rejoin
my favorite part of this story is when i got banned for "hacks" as if there are hacks that makes you invisible and immune to damage
anyways i think the issue might be with how the vanish plugin activates
I recognize these symptoms well, if successful in replicating, make sure to check the logs of your client, also try interaction with something such as a furnace or chest, I have been dealing with a nearly identical issue assembling a modpack for me and some friends in 1.18.2, and it was affecting singleplayer as well.
(The conflicting mods that caused the issue in my pack are known: Valkyrien Skies and Eureka Airships don't play nice with the ESSENTIAL mod, they cause enough log spamming to result in partial desync, player can permanently affect the world with limited interactions; they cannot be affected by anything, dismount, use commands, cannot right click interact with anything, and can attack and destroy entities but recieve no drops)
Might be geyser or bungeecord/velocity sending packets incorrectly. if you're using any paper forks like multipaper, it could be not updating the player puppets properly. or an improper viaversion version detection
In the past on bedrock edition skins that were more than a certain amount transparent would have the transparency turned to black. A few years ago I realized however that there was no longer such a mechanism and skins could be any amount transparent, so on a realm I was playing on I messed with ppl using a 100% transparent skin. The only downside was that ur shadow could be seen if ppl looked closely tho on some blocks and such shadows aren’t visible (like glass or on the snow carpets when u stand in em) and in tall grass or flowers they’re hard to see.
Ofc a lot of servers have their own mechanisms to prevent these skins from working unlike in the past so its only really feasible on multiplayer with friends And in realms
This bug seems awfully similar to the 2b2t Immortality machine which FitMC even did a video on
I've done this before on modded and vanilla servers, it would only happen when my IP got reset (which is every night at around 1am, don't ask why, my ISP is weird)
I would assume the handshake between the server and player that's supposed to authenticate them goes through but not all the information arrives, which is how the TCP/UDP protocols work (throwing data into the void and hoping it arrives at the correct location). This would explain the default skin being applied after death and invisibility, the server has acknowledged the connection but just throws out any user data/doesn't get it at all like location updates or even the skin.
I've also had this happen on a different ISP where we didn't have a landline so they gave us a sim card that would go in the router and serve as a mobile hotspot of sorts. It would sometimes get overloaded with everyone being connected and me playing at the same time so I would get the same connection reset error. This also aligns with the guy using his phones hotspot to play.
Hope the info helps!
I once had a bug on your server where the damage was so delayed that with a single totem I could win every fight but I think it was a one time occur
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.
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)
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.
Hey Epic, are you ever going to check out Vintage Story public servers? It would be a neat topic for a server expert, and nobody seems to really have explored them yet.
my theory is especific packets are being dropped such that the player goes on a limbo state
One day I kept getting this bug a lot on the server Diamondfire, it was back in 2022 when I had really bad wifi and my parents were watching Netflix so they used about 90% of the internet speed leaving me very little of it and it was pretty much unplayable, so I tried to switch to my hotspot which was better than my wifi and I joined the server, and couldn't use any commands (I wanted to use a command to get to a minigame I was playing) I did that multiple times but it was still happening.
I'm pretty sure this has happened once or twice on hermitcraft as well
