Between Turn Crash and Spinning Hourglass

[Weebeast]

I've encountered a crash during AI turns so I reloaded hoping it'd go away. I reloaded, activated a script and hit end turn. The second time it didn't crash but the hourglass kept spinning and I couldn't do anything except viewing settlements. I reloaded again and thought there's something preventing AI for completing its turns so I "removed" my pieces including the one that was besieging that city west of Alexandria. I hit end turn. AI completed its turn(s) and Seleucid attacked my army. I was happy to see something different, I autocalced and was back to my turn but hourglass spun again.

I consulted Frequent Issues and search feature. I've learned about the rebellion. So my journey begins. My courage waned as I went through barbarians cities, greeted by foul stench and man titties. Just outside the city wall of Ebunorum, I've met a man name Beredos. I thought he was just another brigands trying to steal my eagle but he's not Gaul. He spoke of an tranquil island just a bit north of Belgae. So I wondered what brought him to German lands?

By the way, I've looked around for rebelling cities mainly in conflict zones but not found any. Well, I didn't check all but my question is how come I didn't crash when few of my cities rebelled before?
