Sometimes when I place any mirror in a basement, the stairs and build mode items glitch (while in live and build mode). I've tried fixing this by repairing the Sims game, updating it, and so on, but nothing seems to work. I do use mods (MC command center and ui cheats only), and I've tried playing the game without those mods as well as downloading the updated versions and playing with them to see if that was the issue, but it wasn't. I'm not sure what else to do.
I play on a MacBook laptop, if that information is important to this bug or not.
