This has started to happen to me recently, and it makes my saves unplayable. It happened first early on in the Grand Campaign with Rome, which I abandoned because I wasn't really into Rome that much. Next, I started a game with the Iceni in Imperator Augustus. I had just taken over 3 cities in Great Britain, and I was really getting into it, when I got hit with the AI turn crash. Every single time it would crash when it was Antony's Rome's turn. I tried a few fixes I found online, but none have worked. Can someone help please?
