I've got the room...but my things appear on both sides of the room! (mix pirates and yacht) Does anybody know if the things can appear on only one side? Because I'd like to organize the pirate side without appearing the yacht things...
Hope you understand me!

If I understand you right it cannot be done. It is still just one room with 2 possible looks, not 2 different rooms in one. So it does not matter which look you chose items are still the same and in same place. This was always working that way, for example for Garden or Haunted Castle room.
