AI zombies at the moment are enabled by default in vanilla servers in some gamemodes, such as Arena, campagn etc and it's a real problem in the game. Because of this change nobody is playing those gamemodes such as cafe county arena, I know that cafe county arena was hated but Id rather have that over stupid ai zombies in our beloved gamemodes.

Simple as that, disable AI zombies for all gamemodes but PvE.
