I put floor tiles on my castle floor and then placed a rug from the heritage token on top of that. When I came back later the rug was no where to be seen. I removed a floor tile and there it was. I tried placing it again and it went down just fine. Came back later and the same thing. You cant raise the rug and you cant lower the floor tiles. I had to remove the tiles on top of the rug to see it.
