Good hunting Stalkers and stay Cheeki Breeki. I suspect that the problem could be related to Arsenal Overhaul, due it is problem that appear with that psy helmet equipment. It looks like that one of those addons is causing the problem. Same problem here, so I reinstalled CoC 1.4.22 and I also reinstalled Doctor X Questlines 1.25 and Arsenal Overhaul 3.1 (otherwise I am not able to start my saved games).
