I'm having the same problem and if its a text edit error, must be the unit names sections. Mine has been freezing about half an hour to an hour into playing, doesn't matter if I'm attacking, waiting, or even in a shop buying equipment. I've only changed a name in the text editor and gave the name to one of the starting generics.(the ones you get after the opening battle) Didn't change any of the sprites, abilities, jobs, or events.
