For some reason every mod I have tried seems to stuff up NPC behaviour at some point or another. I dont know what is going on. They are either trying to shoot something that is hundreds of metres away out of sight or they are stuck behind a wall or they just wonder off and get killed. This leaves me unable to play the game the way I want to like completing quests for Stalkers. I have tried many mods and it happens on all of them, the only way it doesnt stuff up my NPCs is if I play vanilla Stalker. Hopefully someone can help, thanks.
