THere are several serveradmins with this problem. --http://www.exilemod.com/forums/topic/question-re-ryans-zombies-and-demons/
Proximity zombie spawnerscript + Zombies and Demons works with Exileservers because it´s the script that´s setting the damage, but I think it´s better to use the "zombies and demons" built in zombiespawners for better "adjustments".
Is there a quick workaround for this? Like an edit of missionfile INIT? I have tried some eventhandlers but can´t figure it out
