Oh, sorry, not being clear enough. I meant RTW/BI/ALEX.

The engine can just handle some amount of buildings in a city, if there is another build, the game crashes. Should not happen to a human player, as there are not enough buildings. However, the script and AI places buildings, i.e. government types, in a high rate, so that could fill up the place.

Did you try to fix the rebellion in your town by using the advices given in the Frequent Issues? Please try that before I try it at my own build. In case there are problems, just post back here.
