About the crashing...

After being highly annoyed that I had to restart, I learned the battle crash only happens on a quicksave. So if you load the save like normal, youll have no issues. (At least I havent yet, Im also pulling down the drop menu to be safe) I think there is something wrong with the way it quick saves, but if you load the quicksave, save your game, go to the title, and load normally, itll work normal again.
