I have several cities that won't grow beyond a certain point. After it reaches size 6, it stops growing. I have surplus food, however the city display shows 'turns until growth' as 9999.
Other cities seem to grow just fine, with the same buildings as the cities that won't grow beyond six.
I'm unable to find anything regarding this in the manual.
Cities on rivers can grow beyond size 6 (up to 12 I think). Cities NOT on rivers require an aqueduct, again until size 12. Beyond size 12 I think you have to build a hospital.
