Sims keep filling up empty houses
So, I've been having this issue for a while. Sometimes, I will play my sims game and I see that random sims fill up the empty houses. I know that some people like to fill up the houses, but I hate it. Especially when they keep filling the houses and I have no empty houses to move my families into. I have disabled the option to fill the empty houses, I have no mods that would cause this, and it happens so randomly. It doesn't always fill up the houses every time I run the game, but when it does, I have to individually evict every person, and it's really annoying. I've been getting rid of some of my old cc, but I don't have any gameplay mods that would cause this to happen. I have MC Command Center, but there's no options that would cause sims to fill up houses, from what I've seen. Other than that, I can't figure out why my game would do this. Help would be greatly appreciated. Thank you.
