🚨BUG REPORT 🚨

I just wanted to report a bug I've been having in ts4 high school years. I just got the pack yesterday and I'm renovating the hs and the lockers are broken. When the lockers are outside of a room they're fine but when the lockers are inside a room they become black. I did already repair my game and I don't have a lot of mods so I don't know what happened. Can someone please tell me how to fix this?
