CTD when trying to take settlement

[Mony]

Playing as KH and trying to take Ankyra and when I go into the battle loading screen it CTDs. I checked three times before posting to see if it wasn't just a glitch, but keeps happening.

I believe there's a log thing to post for these kind of issues but I don't know how to find it. Also should note that other than selecting factions and getting a CTD, this is the first one I've had in game. But it seems persistent.
