I just started to have CTD's when I try to sleep. I can't even play the game now because of it because I can't rest. I checked earlier saved games and it was also happening at least from the time I was in the cave under the castle on Bone Hill. I have checked all of the logs and there isn't anything showing for the crashes. I know it isn't a problem with the game since I have a save from far earlier in Chapter 2 and I can rest fine if I load that saved game.
I found another bug that is really annoying. I have found two blank items (no icon and no name) in the castle on Bone Hill. The biggest problem with this is that they can't be removed from your inventory and prevent you from picking up more stuff. I have to save and reload to get rid of it and be able to pick up things again.
This has been happening since Beregost and always happens in certain buildings. The first time it happened I was able to get free once when I was stuck upstairs by using another character but when my character gets stuck on the stairs like in the above picture it is impossible to get unstuck without using ctrl-j. (atleast until I can get teleport or dimensional door which will be a long time)
