I'm getting really annoyed by this furniture bug.
-I'm not really sure what or how it's doing it-, it duplicates some of the furniture and sometimes makes you lose one furniture in the process.
RIP clock.
Edit: it's also pretty broken. I got the gist of how it works, you basically place down the furniture you want in the manor, go to another room, click on the furniture you placed (it's font has to be shaded, like it has been used or it's the only furniture you have), and then place it in the manor. Clear the room and sell the heavy amount of furniture you got from that.
Weird bug or a feature.
