Game Closes

I have a problem, the game closes every time when I try to build in a settlement.
When I try to build a building in Carna the game closes half way through ending the turn. Of course the obvious solution is not to build there but I don't waant tot do that, can someone provide a answer please.

You should post in the tech help forum. See https://forums.totalwar.org/vb/showthread.php?t=83728.

I once had this problem when I accidently repaired the AI government. Make sure you destroyed them all.

Building a building crashes sometimes happen when there are two of the same building tier in one time, such as government (as stated above).

Also, are you using the "process_cq" cheat when it crashes? Because that will cause crashes in certain cases.
