I am having the same issue. The game either crashes when I attempt to save or it stays stuck on the save game screen. It really sucks playing for an hour or so (when I have limited time as is) and then I go to save and it crashes. I've had to replay the same battle about 10 times now. PLEASE FIX THE SAVING ISSUE!!!
