This is kind of an annoying problem, not really serious. In this one city tile I'm working on, the game freezes whenever I quit. I've only noticed it happening in the one city tile so far. I can save the city fine, exit to region fine, and open it fine. It just freezes when I go to quit to desktop, and it's getting annoying having to restart my computer every time I want to quit. Could this be caused by any lots I have plopped or grown?
