This is a SourceMod Extension that fixes lots of bugs and improves the existing behaviors of the survivor bots. This project was made around April 2020 and had been in development for about a year but has been abandoned meanwhile since I don't have the time to maintain it. You might have to modify the source code in order to compile it.
It was originally made for the Linux version of the game but later received Windows support as well; however, there's an issue with custom behaviors on Windows which causes a server crash.
I suggest not using this extension on your server but instead, creating a fork and editing it or using the code and creating your own version with it. You can also use this plugin as an alternative if you want to modify behaviors using plugins.
If you decide to use it anyway, make sure not to use my other survivor bot fixes since these fixes are already included in this extension and might cause issues.
