Re: [FIXED] Objects show up in the sky and on map
Crin shared your save with me for additional testing 🙂
I've had a really good look around San Myshuno and there is a lot of TOOL usage in the world. If you didn't do it, have you downloaded Lots from the Gallery? Or are you playing a save that has been shared with you? It's possible the creators used TOOL and lost items in the world when entering erroneous values. Instead of undoing the placement they simply kept trying to place the same object. It certainly looks that way with the festival stuff.
I noticed these lights above a penthouse:
When I bulldozed the penthouse they disappeared.
I also noticed these on the apartments:
(Edit - ignore this, in a clean new save they still appear so are Maxis placed)
I'm not sure how you're going to get rid of them unless you trash the save and backups and start again. You could bulldoze all the lots and see if that works.
