I enter the best most Bethesda patch not ever, for fallout 3 on pc: “game will now run”
@@Dap1ssmonk i finished fo3 on pc a week ago, wdym?
@@vivious_ it didnt work on pc for a long time, its a somewhat recent update
@@vivious_ this was years ago. Basically fallout 3 used the games for windows (this was during vista) service way back in the day near launch, and when that service was scrapped, fallout 3 would crash when you tried to load it on pc. This lasted about a year before Bethesda fixed it.
Sometimes I wonder how people even come across these bugs, like these are such specific inputs and when you account that pretty much no one uses the Buffalo Steak Sandvich, it just makes it even more surprising that these things actually get discovered in the first place...
Actually I've been using steak and fists of steel. But never switched to sniper while eating it
@@realdragon It also only works in spawn, since doing it outside of spawn just kills you.
time. with time, many weird obscure bugs are found in just about anything.
It's why major cybersecurity issues like shellshock, heartbleed, and log4j were such big issues.
these issues had existed for years before being discovered, but in that time the relevant code had been implemented into millions of devices and websites.
Nah, man, Fat Demoknight is a fairly common troll subclass and fist of steel are the best heavy fist to combine with steak for a fun game where you actually have a chance to catch and kill someone before they kill you with their ranged weapon.
Just rarely anyone ever thought of switching to sniper while eating steak at spawn.
Maybe someone was trying to sneakily get full Bushwacka crits by using a class change, and happened to have the fists of steel?
Hard to believe there has been such an easy to perform bug that could have crashed servers like this all this time. TF2 could have been unplayable if this got out to the masses before the fix.
Makes you wonder how many (if any) catastrophic bugs exist and how many were patched before becoming widely known
If the hackers/trolls found out about this before Valve fixed it...
VIdeo games are monstrously complex and there's always, always bugs lurking like this. You just gotta hope you fix them quickly, ideally before release.
@@hikari_no_yume yeah, I don't know a single multiplayer game that never had a "server crashing" type of exploit. And in games like tf2, that have so much content, you are pretty much doomed to have some of those server crashing bugs
@@hikari_no_yume
I wonder if someone will develop an AI that dectects bugs in the future.
I am actually slightly disappointed that switching to sniper while the heavy eating a sandvich animation was playing didn't just suddenly show sniper eating his rifle before the game crashed.

@@LocalPlagueDoc still a bit wierd but I understand this much better now, thank you.
This is awesome, thanks for bringing this to our attention 😎
At this point, it really feels like shounic knows more about TF2's code interactions than anyone who isn't actively developing it.
What about cheat developers?
You act like there is _anyone_ actively developing it.
@prehistoricam i hope the cheat devs move on to free to play mobile titles. Those titles deserve it
why would the average person who isnt actively developing it know about niche code interactions
Not that hard, since no one is
This sounds like dark magic. Remnants of a forgotten weapon, summoned in an obscure way, destroying the world(server).
Program developed enough isn't distinguishable from magic, I guess
Yes
Instalation Wizard
Oh hi Dewill. Yeah i fully agree lmao
Source (of this): Spaghetti
I'm pretty sure if magic were real, breaking it down step by step would cause it to cease being magical. (Aka. that's how electricity works)
Ate his gun in the style of the trope, clearly. All those bots possessing him removed his will to live.

*GOODBYE CRUEL WORLD*
I wonder how many heavys rageswapped to sniper while eating and accidently crashed a server. I'm sure it has happened naturally once. Also crazy that a server crashing glitch has been in the game for so long without being found/abused lmao
snipers are the guys who might rageswap to heavy lol, not the other way around unless the person rageswapping has really good aim but is getting owned in close quarters.
Not just that, but they'd have to rageswap in spawn.. While eating the steak. Most heavies don't eat a steak leaving spawn, and even fewer would eat it then intentionally switch class. Even fewer to Sniper of all things.
@@iamnevrchange.9570 only Bing Soy might swap to sniper from heavy
Makes me wonder how many other ways to break the game there are that have just never been discovered yet
I love how the heavy stares in frustration for the few seconds after the server crash is initiated, like he's fully aware he just broke reality and this is not an uncommon occurrence.
The funniest thing about this is that it demonstrates how little people who play serious Heavy swap to sniper. It's taken since that weapon was scrapped to now to for someone to perform the bug.
This was extremely specific so it's very unlikely to happen even on an "non-serious scenario"
@@TheMistermastermario Honestly, the setup is pretty decent for a bog standard Heavy doing bog standard things. On spawn or respawn you get to the frontlines a lot faster and safer, and if you're part of a Medic/Heavy combo both of those slots aren't of much use besides utility which those two items give in spades. You don't even have to sacrifice emergency healing your Medic since throwing the Steak still does that.
Probably because it doesn't make any sense to use it in the spawn room.
Even if you are deadlocked in your spawn, there are better classes and better weapons to contest
@@danilkinilya1242 Speed boost for rollout. Gambling you won't meet a melee opponent on your way to the front.
@@Ne1vaan I think the speed boost doesn't make up for the time loss eating the steak...
The Brass Beast spin-up sound has been broken for an insanely long time. If they're going this deep into the game files and also already fixed the Iron Bomber's projectiles, I don't think it would be unreasonable for them to fix the sound too.
can you explain more about this bug?
@@pinkmail6841 basically when you rev up the BB, there's a sudden but brief cut in the audio, the rev sound just stops and then awkwardly continues after a second
The most upsetting part of the whole video is finding out about that sniper revolver that even had animations before it was scrapped, feels bad man.
In an alternate history, sniper bots are even worse as they can pop off up to six kills before having to reload. Truly terrifying.
I wasn't expecting them to fix it robustly, I was expecting them to just remove the entries in the qc file XD
TF2 bugs in a nutshell are like: being able to have unlimited ammo as Pyro by launching 10 quickie bomb stickies into the air then using the “need a teleporter” line then picking up a Scottish Resistance off the ground while then quickly switching to Pyro and looking straight down. And the entire thing is only possible due to an obscure patch released in October of 2015
The Source Spaghetti has no bounds.
It breaks because sniper breaks his teeth,letting out a scream and causing the server to force a crash
"Now I gotta make a necklace outta your teeth, bushman's rules." those are his spare teeth
probably used those teeth to make a chair
But heavy has the robo sandwich...
1:27 that's the most pissed expression ive ever seen on a heavy, he genuinely wants to kill small manns
Wow. You somehow manged to explain this perfectly to me, a person who has litteraly 0 experience in this topic and made it really interesting. Take my sub damnit!
I love how heavy's face kinda just goes "you what" after it crashes
A sniper revolver rifle sounds great, I wonder why it was removed.
We can only speculate.
But you can try it in some way in TF2 Classic
best guess is that it was redundant or didnt mesh well with the existing sandbox. remember that the panic attack is often criticized for lacking an identity to distinguish it from the shotgun.
It could be less range, lowered accuracy or less effective damage.
Might have just been that it didn't get finished in time before TF2 got put into its current perpetual no-development limbo.
And a Revolver for Engie
Tod: "It just works."
Gabe: "It just doesn't work."
"The game then tries to access this animation, finds nothing, and explodes."
What wise words
"The game then tries to acces that animation, finds nothing and explode"
Sounds like a regular TF2 tought process to me 😂
(I think some people didn't get the joke of failing at your job and ending up killbinding wich is a common thought procces for TF2 players)
server killbinds after failing to access the non existent animation
to my knowledge it's a staple in computing to always assume everything works perfectly as intended, unless the program is specifically told not to, how to check and what to do in such a scenario.
So if the program tries to load something it assumes must exist, but that doesn't actually, it just kinda stops.
because as far as the program is concerned, the entire fabric of it's reality just fell apart.
So any program would do that, unless it has specific instructions on what to do when things it tries to call do not exist.
It's just normal programming. Nothing to do with TF2 in this case
Kind of yes... In case of tf2, which is written in c++, if you try to access an object (memory address) you don't own, it's the operating system that says "nope, not giving you that" and you get what's called segmentation fault exception.
Now, a program might be prepared to handle the exception but it costs performance and, well, no one thought this can happen in the first place, because why wouldn't you trust *your own* animation system? Lol
@@JM-dq7xnmfw when segmentation fault (core dumped)
Love that at 0:20 Heavy's face goes all serious like "Oh blyat, Heavy shouldn't have done that".
This game really is held together with super glue, bubble gum, and morally grey intentions, isn’t it?
Super glue? Nah. Average glue.
@@EnderLord99 Nah not even glue, just some of Scout's sticky mad milk 😳

@@wilmercepeda3611 wrong,its held together by a coconut
What I learned is that Valve has so much content for tf2 they just scrap nearly finished projects like its nothing
Just because it was almost finished doesn't mean it worked well. Valve's game design philosophy has always been to tweak and test things to perfection and scrap what doesn't work. For better or worse.
@@517342 Well if that's the case then why is the Gas Passer so terrible?
@@hoodcate Fair point. If you ask me I think that at that point in time they had already lost their way.
I think a lot of things they added in that update felt desperate.
@@517342 Ever saw the hunting revolver the TF2C sniper has? It's seems like a good concept, could perfectly have been introduced to the game with the way the did it with this one. (Im aware of TF2C being more recent that the scrapped revolver weapon but it wouldn't hurt seeing it introduced like that in the future on vanilla TF2.)
@@hoodcate adding a terrible weapon to the game doesn't really affect anything, it won't make the game unplayable like adding an overpowered weapon would
This is a really important fix that thankfully came out before any real bad characters found out about it. However, I think them adding that scrapped weapon would've been a cherry on top of trying to patch up the game. I don't know its history at all, or what it was meant to be, but I know the fan base would have gone nuts if anything besides code improvements are ever added into the patch notes :D
imagine if every bug report was accompanied by a video like this
I can't stress enough how detailed and accurate your videos are. The level of details in each animation is top tier and they are all invaluable to the coherence of the video. (When do you plan on applying as QA to valve ?)
As a programmer, I hope people appreciate how amazing your graphics, animations and backgrounds are. It’s all so digestible. It could be sooo much worse
Thumbnails are amazing too because it's the opposite.
The Vegemite Gunwich
The moral of this story: if you don't have a revolver rifle, never try to eat it.
man im glad valve finally fixed this glitch because i always change to sniper while eating steak with fists of steel
my favorite part is when the server starts lagging and the heavy moves to his idle anim and looks like:
>:( now i can't eat my steak
This is a certified Snipervich moment.
Ah yes, my favorite class, “Sand”
Snipervich sounds like a serbian surname
@@aneurysmjohnson887 "Hey Niko, wanna go bowling? Kosovo je Srbija. Slava Bogu" ~ Snipervich
What's always amazing to me about these kinds of insane bugs isn't how they happen, because I understand that code can interact and conflict with itself in impossible to predict ways, and usually (like in cases like this) the bizarre conflict makes sense when you break down exactly how and why the conflict exists.
No, the thing that amazes me is how people actually sus out these exact activation conditions, or more specifically, what leads to them investigating in the first place? Like, what possible thought process lead to someone trying to figure this out? Servers crash all the damn time, for seemingly no reason, and how/why would someone think that them switching classes at that particular moment had anything to do with the server crashing? Even if they somehow accidentally did it twice, by sheer random coincidence, why would they conclude it had something to do with their actions in-game?
yeah, and why would somone switch classes while eating the steak in the first place
@@algotkristoffersson15 you're heavy, you eat steak, notice spy decloak behind you, you lose all will to play heavy and start playing sniper because piss.
4:43
Heavy just standing there with a piece of meat and a dissatisfied look is really funny to me
Y'know there some sort of robust sense of justice in the fact that I was responsible for the sandvich crash the entire time, and then only finding that out AFTER making a mod to turn the sniper's rifle into a sandvich. Everything eventually comes full circle doesn't it?
So were you playing as a Steak Sanvich Heavy and switched to Sniper often?
@@bobbyferg9173 no, I'm the one who helped make the revolver rifle who's animations were what was ultimately causing the crash. lol.
@@kibbleknight2 Well, lack thereof anyway. On that note, the model looks really cool and well done. I hope Valve implements it in one day.
Literally just the TF2 server having a nervous breakdown when it doesn't know something.
After all the bot accusations and hate towards the class, Mr. Mundy has finally had enough of it.
It was tasty
Apparently this bug fix also fixed custom MvM missions crashing servers if they spawn a robot Sniper with a banner item, which now enables that robot type for all custom missions
Sniper decides to ignore gun safety, collapses reality itself
Ahhh makes sense now. As a wise statue one said, “the answer to life is 42”
I love these videos and tf2 bugs in general. In other games it's just same old bugs (excluding sims 3), but tf2 always has the funniest shit, like this specific bug. It's the code that keeps on giving
Amazing video! A really solid explanation and the visuals really helped drive the point home! Thanks a lot for your effort.
I love your in depth explanations; they're very binge-worthy.
Classes that had revolvers: Spy, Sniper
Classes that never had a revolver: Engineer
The rest are in a "not yet confirmed" state.
I wouldn't say "had" (past-tense) for spy, revolvers are kinda his thing :P
Now I'm just sad we never got that weapon. :(
Hey dude, just wanted to say that I love your channel. These in-depth explanations of the way stuff works in the game are really good, and you present them in a way that makes it really easy to understand.
Absolutely love it, keep it up!
You break down complex game science so well, and to make it fun and interesting is such an impressive talent! Subbed forever, keep bug hunting!
Not gonna lie, now I'm disappointed it wasn't a bug that actually lets us see Sniper trying to eat his gun.
So Sniper didn't just break reality by trying to eat his gun, he broke reality by trying to eat a _nonexistent_ gun.
I thought this update was fake until I saw the tf2 update page LOL, thanks for the informative video!
Ahh, I’ve been waiting for you to cover this and I am not disappointed.
The issue being with "ghost" animations makes total sense. Optimizing a video game often means removing any sort of just-in-case double-checking. No time to stop and validate animation calls when you're going for a high framerate - if you asked for anim 10, and the file has an anim 10, it's loading whatever that's pointing at and doing it, valid or not
Adding a try...catch doesn't impact performance. They probably just didn't account for a niche case like this.
Not to mention, optimisation on such small of a scale is practically nonexistent in the modern world. Modern as "in the last twenty years or so".
I swear tf2 is one of the most absolutely shattered games code wise
I met someone on tf2 with the name sniper trying to eat his gun, now i know why. Thanks!
Wow, cool stuff 👾 Thx for the video.
This reminds me of the Egg Missile Crash in Paper Mario. The crash happens only when fighting a specific boss, Lava Piranha, only when you use the effect of a specific equipment called Double Dip to use to use 2 items in 1 turn (usually you can only use 1), and only if you use the item Egg Missile (which you need to go out of your way to craft) as the 2nd item
Fun Fact: I somehow did this by pure accident myself. Don't ask me how lol
someone probably had some loadout with steak and steel gloves (forgot name) and desided to switch to sniper when they changed their mind about playing heavy while eating this steak, then the bug was reported.
Awesome explanation, great job!
Thanks for explaining!
It amazes me that they didn't implement a system to simply wipe the slate clean when switching classes, that seems like such an obvious thing to do to avoid exactly this kind of issue
Not to mention:
1. Just delete the sniper animation files that aren't used
2. Couldn't they have a system where if the game loads an animation that doesn't exist, it just ignores the request, rather than crashing the entire server?!

Excellent explanation on a trivial matter. : D
Sweet. I was hoping for a video on this.
You explained something this complicated really great and basic, great job!
I love all the diagrams, makes everything easier to understand
That was a more interesting answer that I expected
every new thumbnail you create is a fucking treat by itself man
Tf2: oh no i found an empty file im gonna explode
GMOD: I found an empty file. I'm just gonna be this annoying little error gui in the top left of the screen. Nothing can hurt me. I am invinci- [crash]
Great video as usual. I wonder how many of these extremely specific bugs still exist that we just don't know about? There's so many possible combinations of weapons, taunts, particle effects, cosmetics etc that I feel like it's almost guaranteed there's some weird bug out there, like "the server crashes when you wear this specific hat and do this specific taunt, but only while being airblasted, and only while holding this specific weapon".
Interesting as always
i absolutely love these types of videos because i mod l4d2 and alot of the time they are animation related
the costume thumbnail alone is absolutely hilarious and deserves a like for the video as a whole.
Wow, thank you for posting this after they fixed it, would have been devestating if ppl found out this en masse
After he explained how TF2 animation ids work, I instantly understood how it works. Nice video!
I like how pissed Heavy looks when this is attempted.
props for making a thumbnail that doesn't demonetize your video
This is glorious.
“Finds nothing and explodes” sounds like my dad
Honestly, the most heart-breaking part of this entire thing is the fact that they scrapped a Sniper primary when it was basically ready to go. All it needed was stats, which would've just required modifying the existing sniper rifle's code to operate how this new gun was intended...
The issue was the stats, they likely couldn't balance it.
An easier to use version of the sniper, which in my experience is easy to use with a little practice like anything, is near impossible to balance. It would either be training wheels or something every single sniper uses all the time.
I find it pretty nice that they sorta returned to more jokey names for the patch changes. Reminds me of the old updates.
Fixed a bug where players could be teleported to hell and not have visible bumper car
Your video is really good and all but can i say i love the thumbnail? Lol
This makes sooooo much sense.
As a software engineer I thoroughly enjoy these videos. Great production and analysis. Gives the game this down to earth appeal, somehow. Thanks for your effort, and keep em coming! :)
Mmmmh that graphic design and composition is just so hot
The use of colors too it's just so perfect
It's cool that the game calculates animations on server side, which will make all players see and hear same thing at same time.(Much better than the other games)
That thumbnail is a work of art.
Dude that revolver sniper looks so goddamn cool. How are you gonna tell me we were that close to getting that beauty in the game. I don't care if it's just a reskin, it looks stellar.
