Since this a beta server I understand that you want to know about things you can do and can't do. I've noticed this about the population. If you have a population of 550 ppl and reach that maximum with buildings to allow that population it is good. When you have reached this limit if you tear down your housing/resident your population stays the same. That is without the proper buildings for that limit. Just bringing it to your attention because I really enjoy this game. Thank you
