CTD at end of turn

[Anduin1]

Getting a CTD ~52 turns in at the end of the turn. Posted my error log if anyone has any idea what I can do to fix this.

Ok I've been playing around with the saves and it seems to come down to the city of Marrakesh. If I try to siege it, or capture it the game crashes on the next end of AI turn. I just made peace with them since it was the Moors last city and I'll leave them alone since I don't know what else can be done.

Have you tried to send a spy in it in the hope he can open the gates for you? Then, you can try to go directly for battle and see if you still get the ctd.
The other solution is to use the console and to use the "destroy faction" command to remove the Moors. That settlement will become rebel and you can try to conquier it again.
