New crash apparently caused by an incorrect gamedata #6

The server crashed the moment I killed a spitter on dead center with a fire axe. It was a versus game. Accelerator is suggesting it's likely a gamedata fault, and this plugin's smx is mentioned in the raw section.

Does the crashing always occur or it only happened once?

Yisus89 commented 1 year ago

It only happened once. Since then I have played at least 8 matches of both versus and coop and never got another.

The gameserver crashed again. I wasn't present when it happened but we have the dump

server_srv.so!bool NavAreaBuildPath<ShortestPathCost>(CNavArea*, CNavArea*, Vector const*, Vector const*, ShortestPathCost&, CNavArea**, float, int, bool) + 0x490

The issue is still referencing bots though this time it says something about the navs. Accelerator is once again saying that it's likely a gamedata issue.

I am not able to reproduce this crash, though it's not a one time thing. It happens again and again, it's only a matter of when.

These are some errors that are showing up with the latest version of this plugin. Perhaps fixing them can help with this crash.

This user looked at the gamedata of the plugin and it seems like ZNK12 has a mention in the gamedata but not ZN16. _ZN16ActionsPropagate14ProcessHandlerI12ActionResultIvEJP11CBaseEntityfEEEN9SourceMod10ResultTypeEiP6ActionIvEPT_DpOT0_ + 0x206

So this here is not present inside the gamedata which could be the reason for this crash. That's following accelerator's hint on gamedata.

We have 2 hints that this gamedata is the issue: accelerator reporting it's likely to be a gamedata's fault and the crash not being replicable and happening seemingly at random.
