Some Build Your Room achievements work weird.

The achievements that requiere 170 Bunny Run Fields, Roller Rinks and Ice Skating Patches don't recognize 170 of their respective floors on the room, they only recognize if you have placed 170 of them. That means you can do all of those achievements with only 1 of each floor. Also, the Room Architect one, the one that requieres Black Holes, doesn't work at all.
