I know sometimes it is hard, but proves the need for playtesting even more. I have been fighting a few hours with one of the more popular spas from the gallery. Nothing major really, except minor things like two speakers too close so you get a really annoying mix of radio stations.
BUT it turns out the bathroom / showers on the very top floor are unusable. And not for a logical reason. As far as I can tell MOO is NOT used, I can place the same items in the same place without it. But the Sims cannot use anything placed along the back wall. I had to "wall off" the back wall (basically creating a fake "pillar" and move toilet and shower one square forward into the room for them to be usable.
And in this case it seems like a bug in the game since there is nothing that indicates there's an error when placing items (NO items could be used along that wall, not even viewing statues, yet everything could be placed there without MOO, and there was just an empty floor in front of it).
