I'm currently set up in a two story building, and while I have the ground floor and parking lot set as my base, they don't recognize the second floor as part of it and barely ever go up there, even though that's where the food is. Does anyone know if the mod can do multi story bases, or if it cannot handle that? I was able to set the second story only as a base and that worked, but obviously not ideal and I'd rather them be downstairs than confined upstairs.
