L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

I've started this topic in the hope to keep everything in 1 place, instead of bumping various plugin threads, post issues here and when they're fixed someone can bump the relevant thread with fix details.


Developers:
Mostly vtable offsets need updating. These can be quickly fixed by checking last version vtable offsets against new version. Drag and drop the old/new linux binary into https://asherkin.github.io/vtable/ and compare if offsets shifted (seems most things changed by +1 except very early vtable functions).



disconnected (reason "Disconnected: Issued too many commands to server"):
Put sv_quota_stringcmdspersecond "999999" in cfg/server.cfg



Server crashing?

• Set cvar sv_voiceenable 0 to prevent server crashing - game bug. Valve update fixed (25-Sep-2020)
• 2 sourcemod gamedata files require updating if your server hasn't automatically updated them.
• Requires SM 1.10 to stop gamedata being overwritten.
• Check for plugin and extension updates (bunch listed below, not complete list - post links to updates I missed).

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Hi there, I'm the guy who posted the updated sourcemod gamedata for the update.
I got trusted with early access to the game and I've been able to inspect some of the binaries to find out about what may break sourcemod plugins/extensions.

I can't talk a lot about the update, but in hopes of helping this update go smoothly,
I wrote up some notes about the major breaking changes I found, which is available as a Github Gist: L4D2 2.2.0.0 gamedata fixes.

If you make extensive user of vtable offsets or memory address reads in your gamedata you might find useful information here to get your plugin ready.
Also, there have been a number of bugfixes in the game, for things like Charger Chest-bumps. So you might find that some plugins become redundant after the update drops.

I apologize for the selection bias of plugins I've tested, but hopefully some of this is generic enough to help.
I'll be around on the SourceMod discord today and can try to answer more questions.

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

What about l4dtoolz? https://github.com/Accelerator74/l4dtoolz
Will the signatures change?

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

I've always wondered about this, and it sucks theres no gamedata and hardcoded. They didn't change during the last major plugin breaking updates (The Passing and Steam Pipe - which broke many things), so I suspect this semi major update wouldn't break it either.

Edit: Have locally updated many of my plugins in preparation for the update with what's knowm to change (vtable offsets) and I'm assuming the melee weapon class/script names which I'm pretty sure will be correct so all my melee plugins will be updated straight away. I just want to verify everything before posting so waiting for the update.

For all 3rd party plugins, a post here mentioning which plugin or whats wrong will help. I can't review them all but most will be simple gamedata changes (especially if it's just vtable). Some common plugins I'll update to their threads posting the new gamedata (after I'm done reviewing and posting my stuff), at least it seems a bunch of people will be helping update so should progress very quickly.

Servers may crash with vtable changes because the wrong function is now being called with the wrong args, that's the problem with vtable changes it's not easily known that they are broken unless the server crashes or you specifically test something and not getting the expected results. Signature changes are much easier to detect since most plugins written correctly would throw an error about wrong signature (unless a signature matches something new - again that being the wrong function so would probably crash server anyway - and with that Accelerator extension would help pinpoint if required).

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Ok, hopefully it will work, but here are a couple more extensions that begs the question :)

Pounce-Damage-Uncap: https://github.com/Accelerator74/Pounce-Damage-Uncap
l4d2_tickrate_enabler: https://github.com/Accelerator74/l4d2_tickrate_enabler

And still interested in the question. The new melee weapons are named shovel and pitchfork (for scripts/console), is that right? https://github.com/Accelerator74/l4d...tension.cpp#L6

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Yeah those are 99% the melee script/classname.

Those extensions probably won't break. l4d2_meleespawncontrol extension is old and superceded by Info Editor plugin which handles the same + many other features that servers and other plugins have been taking advantage of. I would recommend people switch over to that instead of something that's hardly supported.

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Definitely if you are using dhooks :) Not all my servers need dhooks, left4downtown or left4dhooks. Therefore, I prefer to use the simplified obsolete version, l4d2_meleespawncontrol :)

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Well since you've been known to compile extensions, you can provide support for those! That would be greatly appreciated. I suspect most will work fine, l4d2_meleespawncontrol will need an update for the 2 new melee classes. L4DToolZ we'll see but suspect fine also, if even required anymore (screenshot showed 20 players in 1 server testing new update...)

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

It would be nice if the expansion of the slots was already in the game initially :)

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Sounds like it's not a stock feature but L4DToolZ still works with the update. So no changes.

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

I didn't test every feature of L4DToolz probably, but we had it installed on a server and had 9 players in, without making any changes to it. I think it still works.

I just checked the sig in pounce-damage-uncap and it looks like it is stable on the new update.

We also tested tickrate-enabler and it seems to work fine as well.

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Very good! thanks :)

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

My servers are crashing now, waiting new SM version and also plugin's gamedatas.

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

SM GameData changes here:
sdktools.games/game.left4dead2.txt

sdkhooks.games/game.l4d2.txt

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Server running for the last 30 minutes no crashes yet.

Thank you Silvers!

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Some servers are still crashing with segmentation fault after updating the SM GD files:

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Hello, I have a problem, when I update the game, I select the campaign, it loads halfway and the game comes out, I have a server of 8 people, will it be because of the plugins I have? :(

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Left4Dhooks update pushed to main plugin thread: https://forums.alliedmods.net/showthread.php?t=321696

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

We've been getting a bunch of `CNetChan_ProcessMessages` crashes on our our competitive servers. Wondering if anyone else is seeing the same. Haven't been able to pin it down to any specific gamedata/patch yet :(

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Getting the same crashes every 30 min or so engine_srv.so!CNetChan::_ProcessMessages(bf_r ead&) + 0x2ba

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

What plugins/addons are you using? Our servers are using quite a few (you can see them all here) and I'd love to see if we have any overlap

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

I notice that sometimes the server would be running smoothly and then start crash cycling with segmentation fault, probably just need to identify which GD files are outdated...

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Trying now.

EDIT: When I use microphone server crashes, other players can use it. Maybe because I'm an admin?!

Crashes.

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Yep same here, but normal players and admins can use the microphone.

I can't andthe only difference is that I have root flag.

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Using any of the voice extensions? Maybe actual game bug not related to plugins? Would be good idea to test without SM/MM and see if that still happens.

(all my plugins updated, left4dhooks gamedata fix in this thread but still not fully tested and known issue is addons eclipse not working).

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

I have crashed valve servers (vanilla no sourcemod). This is an issue that came within the update.

PS: You said all your plugins are updated, but you didn't post yet?

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

They are posted, look at 1st post links, didn't bump all threads but most. Pushing a left4dhooks update now to it's thread.

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Ah oh saw it now. Thank you!

About this mic issue, until valve fixes it, is there a way to solve this? I tried sv_voiceenable 0 dut it didn't work.

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Guess I'm late to the party. Lets see what else is broken.

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

There is a player on my server crashing, we advised to not use microphone, but this player wants to crash the server.

I tried the accelerator crash log, but it does not save the message with the players IP.

Is there a way to block voice by plugin?

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Looks like the update has more advantages than I thought.

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

For some reason after this update i keep crashing with sourcemod..

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

also is there a new gamedata? and how i update it.. im new to those things

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Links and info in 1st post

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Could this be related to the crash everyone is having?

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

Thanks silver now my server isnt crashing anymore :):):)

Re: L4D2 - The Last Stand Update - Issues and Bugs - Mega Thread
 

I have a local server. It doesn't work anymore after this update. I tried to put both files in the gamedata folder and the server crashes and closes the game.
