Game fails to save and close

Game freezes during save and close or click back to main menu (after death), and I lose all activity from the point I entered the game. This started yesterday when I received the 1.1 version on my iPhone. It happens almost 50% of the time I hit save and close (4/9 times). It puts me back in the last room with a bed that I was in prior to the issue. It's basically made the game unplayable because I have to save and close every couple of minutes or risk losing anything I've done.
