[ARCHIVED] Can't make changes to build

Yes, there are no mods, and I created a new save.
The problem is still there. The build mode stops working after a few minutes. I can't delete or move an object, even though the sound of the action remains, but nothing happens to the object. If I try to save the game, the save screen will play forever until I force close the Sims game. The same thing will happen with the loading screen (it will be forever) if I try to exit to Manage Worlds.
