One mission did glitch out since i couldn't get the papers from some guy into my inventory which was somehow important for mission or ending but that was a long time ago i played it, still fnished the game. Call of pripyat is the most polished game of all stalker games, for some reason i enjoyed call of pripyat the most. Though i've never used mods on any stalker games or most of video games i played.
Call of pripyat not really, the game is pretty enjoyable without mods too.
