[ARCHIVED] Objects flying in the sky: Now on ground or still in sky

I'm having the same, and it's also communicating to all of my saves. 

When we first open the save that has the problem and then open other saves, the issue appears in all of them. However, when we close the game and then open a save that does not have the issue, it doesn't show the duplicated objects; everything appears normal in this case... But at the first moment when the festivals start to happen, the objects are not deleted at the end and begin to accumulate as well.

I wonder where my sky objects fell in other cities

I have a "similar" issue and I think it's mainly a San Myshuno problem, since the apartments I have in that world can be seen from other worlds but I can't edit or delete the objects.
