Sims 4 Household Sims Can’t Enter Or Leave Apartment

For some reason my household sim wasn’t leaving for work and kept getting the skip work notification, so I manually had him step out into the main lobby in the apartment and he keeps getting the bubble over his head as if something is in his way. None of my other sims are able to leave and I have to manually teleport them into the lobby to go to school/work. Sometimes the bubble shows the apartment mailbox as if that’s what’s blocking him from leaving, but that mailbox has always been there and has never given him an issue before. None of the furniture has been moved either so I don’t understand why he can’t leave, and I am unable to manually move the apartment mailbox since it isn’t a household item. 

I do have mods in my game, but when I play as my main household, they don’t have an issue leaving their apartment. I also do have all the packs installed, except for some of the kits.
