Thralls falling through floors

I’ve had to replace several thralls because they fall through the floor and refuse to move out of it. Relogging does nothing as they are still in the floor.

roflmao so this just happened…:

rhino attacked my house. my archers and fighter disappear…idk where they went. my 3 Level 3 dancers come out from inside my house to dance AROUND the rhino.
