It makes no sense how this plugin could cause that. This plugin simply hooks the witch being damaged and triggers her, nothing else.
Would have been helpful if you linked the
other thread you posted about this, lucky I saw it. I tried the "Lockdown" map and they were attacking on bt2 and bt3.
Theres an engine bug where bots stop attacking whenever a pipebomb_projectile is active on the map. If you have any plugins using the pipebomb_projectile entity (for example maybe old Prototype Grenades or old Helicopter plugin might of used this entity, although I doubt they did) that's probably the cause.
