Interesting thing started happening. I started a new region, built the first city over 1 million strong, everything was normal. Second city residential is stuck at 100,000, but commercial is over 250,000 and industy is very strong as well. Started a third city same thing. Strange thing is, in both the 2nd and 3rd city the residential demand only shows high wealth, the other two don't show up. I cannot grow any residential, but the commercial and industrial are strong. Anyone experience anything like this?
