Re: Sims 3 High Rise buildings glitch
@taliadpowell Does this happen in a new save? If you haven't tested already, please do so now. And let me know whether you use mods.
Please also go into Build mode and see whether the building's shell is still visible. With the MoveObjects On cheat, you could actually pick it up; if possible, please do so, but instead of actually moving it, just hit Esc to release it again.
