@PoptartJuniper Yes I bulldozed what was originally on the lot so I could place a new one from the gallery. Also, I don't think it is the problem with this particular build from the gallery, because I tried to place several builds from the gallery to 1020 alto, but none of them could be placed.
I haven't observed this particular problem with any other apartment on the map. It was just 1020 Alto, for some reason. I have read somewhere else that it could be the bulldoze function, but I had also bulldozed other lots, but none of them had this problem. And yes, I have tried multiple times and I am pretty sure the bb.moveobjects is working fine.
It was just really weird that this issue only seemed to be associated with 1020 Alto. I also tried several other things such as repairing the game, clearing the cache, etc., but none of them worked so far ☹️
