--- Comment #29 from Arjun aphull@ymail.com 2012-08-08 12:02:09 CDT --- Just to clarify: the problem does not occur when saving the game. I did not have any issues if I saved the game by going through the menu. It only happens in quicksaves (i.e. pressing 'q') and autosaves (i.e. leaving areas and entering buildings of importance).
I encountered the same problem using 1.5.9.
