I'm running into a lot of problems with massive population growth due to grain imports. I have a lot of Minor Cities at >20,000 population (playing Thrace) which still have population growth due to 7% pop growth from grain imports. I literally cannot keep many of my cities from rebelling without putting a solid governor in them. Unfortunately, there are not enough solid governors to go around.
Is there any way to resolve this without letting half my settlements rebel or modding the date files to remove some or all of the grain resources?
