First Crash and the Lockup both happened on what would have been the same turn. Third time around, that turn was when the spell book opened.

Played another ~200-250 turns with absolutely no issues whatsoever off of the auto save from crash 1-2 and then got another crash (I'm pretty sure it was when the spell book pop up was trying to open, as I was getting a spell every 3-4 turns.
