One of the plot critical NPC's somehow is stuck inside one of the objects, and as a result I can not talk to them due to this fact that he is "inside" the backgroud. And, no, I don't have any saved games where this is not the case. In Act 2 by the way. Any help to solve this clipping problem? Also seems many monsters are spawning on the other sides of walls in the battlefield dungeons, wich is a problem, but not as bad as not talking to the NPC.
