The Zimara house has four gaps in the floor. They are at the gold ovals in the part of the house one enters into first. All four are not far from the walls nearest the ovals. When you look thru them. You depending on your position. Can either see the bottom of the walls and or the clouds below them. I have a screenshot of one that had me at these coordinates and angle of view. 20.36, 0.00, -43.89 Camera heading is 52.70 degrees. It is a cosmetic thing. But it in it's own way affects game play.
