I have a world that I made a city for villagers to trade them. The world is on peaceful so there is no way they can die to mobs and there is also no ways for them to kill themselves from falling or fire. sometimes I will log in to my game and the villagers will start reproducing and when I count the amount of villagers I have the number is decreased. I have very limited resources and trying to get these guys to max is hard so if I could know if I’m doing something wrong or if this a bug that would be appreciated.
