Hello, having an issue fighting the Fatimids with Sicily. Running 6.4 with permanent watchtowers, next heir, and Savage AI.

Sieged by Fatimids in Athens, CTD a couple of times during battle load screen and I attempted some fixes found on this forum with no luck. Installed RBAI and checked the battle CTD fix, didn't work. Already running as admin. with the lowest graphics settings. Have attempted fighting them in other areas and it doesn't matter if it's a siege or open field any battle with them CTD's. Fought a rebel army no problem and then attacked my ally Genoa and again no issue. Have uninstalled and reinstalled both MTW2 and SS to no avail. Have 2 different systems logs.

The second was when I used RBAI's battle ctd fix.
Any assistance is greatly appreciated

Thanks
