@kacebace45 Well, the first problem I'm not sure about.
The second usually occurs when the game is slow to load the townies. It could be because of too many townies, slow computer, or maybe problems with CC.
The third always happens when you created it with a CC that is a recolor of another cc mesh and the CC mesh is gone. Or vice-versa... a mesh with no texture or texture with no mesh.
Sounds like you have CC problems. The third problem you can easily fix by just putting down a different flooring.
Does the problem still occur if you create an entirely new world?
