If someone sleeps in it, then it is a sleeping home. In-game you can check if there is smoke rising out of the chimney.
Yes...but I'm saying that you are not able to take an unoccupied, adjacent house on common land (without any smoke from the chimney) either. I have tried, and all that happens is it says 'processing action' or whatever it says, and then my guy is still idle.
So: i was asking if this is intentional or a bug?
