I like playing as the Kuriotates and I find five to be the perfect number of cities for them. Problem is I prefer playing on large maps rather than huge, so the max number of cities can only be 4. I jumped into the XML and edited sprawling from 3 to 4 (I assumed 3 was just the default used and would increase on map size). In game this seemed to have worked as I was on a large map and my Sprawling trait said I had five max cities. Problem is when I try to build my fifth, it always comes out as a settlement. Where do I have to go to change the number of cities allowable per map for Sprawling?
