Does your house look like this:
WWWWW
W W
W W
WWDWW
W= Wall D=Door
or this:
WWWWW
W W
D W
W W
WWWWW
If it is set up like the latter, then that is normal and it will still work-that is due to the fact the game would have to remember what tile was underneath were it to rotate so it could show the block under it. Drath will change that (hopefully) in a later update.
