possible 1.1 bug

FYI Its 222bc in my 1.1 Romani campaign and i had just taken Arse' from the Carthaginians and was in building a level 2 govt bldg. Arse' still had the oppidium stone walls. The carthaginians beseiged it and when i went to the battle screen to break the seige the game froze. After restarting I went back and tried to resolve the battle without the script. The battle played fine but I got a ctd upon returning to the campaign screen. The third time was the charm as I restarted with the script and the battle played out fine and i was able to continue. Its the only oppidium city I've taken so far so I dont know if it was a one time only problem or a bug like what happened in 1.0. If it happens again I'll post a save but so far its the only crash I've had.
