So my city is about 300,000 citizens but I think it's gotten as high as 350,000 before I decided to raze a good chunk of it to limit the population, as I thought that might help reduce the citizen units. However, it didn't make a difference at all, and I still was reaching near the maximum. I do have a big city size and asset-wise as I play with all 25 tiles and like to use a lot of assets and mods. Mods that I use include ploppable RICO, TMPE, Real Time, plop the growables, and many others; however, these are the most "heavy duty" ones I subscribe to. I also like to build a dense downtown with loads of pedestrian and car traffic and the way I've found to make that happen was to place big ploppable skyscrapers that don't have any population and then using plop the growable to plop down high density residential units within the bigger skyscraper assets (as well as commercial/office units to simulate "mixed use" zoning). I was also using the little "residential control units" that you can find in the workshop but I've since deleted these in hopes that it might fix the citizen unit issue but alas, it hasn't made a difference. Anyway, I don't know if this little cheat of mine contributed to the problem, but I know that that's something I do that a lot of people don't so I wouldn't be surprised. that being said, I've been doing this since I first started making my city, and it really only became a problem once I started hitting 350,000 or so population. Any ideas?? Any thoughts would be welcome.
