I seem to be stuck. I have a city. I can endorse union reps, school principles, and priests. I can build bars, libraries, and churches. 21k support, 3K/s of leisure, knowledge, and faith. I have all the unlocks (under the Leave city button). However I can't seem to progress at all. I can't start a village, town, or a city. It says I need to build City Center. I have no idea whether the game soft locked me for no fault of my own, or if this is the end of content. I'm missing the last two achievements.
