Is there something in the game that when you kill off the Hordes of Chaos, all your cities go into rebellion... cuz it happened to me. I killed off their last city and it told me they were destroyed and then I hit end of turn and every city I owned except for a population 1 city I founded that turn went into disorder.(I was thinking something obsoleted somewhere or something that I missed because I also discovered Military Training that turn.)
Anyways, I went through all my cities and had to turn like 2-3 citizens per city into belly-dancers/clowns they were so pissed. Then the following turn when they returned to normal, I had WAY too many clowns/bellydancers. (Pop sizes between 6-10 Gov. Monarchy) Am I right in assuming it was the fact I killed off the Hordes of Chaos? Or perhaps something else. The only improvements in my cities were shrines and libraries. Can other civs cast anarchy spells on you?
