Basically, any time I try to build or visit a house the game closes. I can join and play, but I try to visit a house, or build in a house, the game just closes. This is really annoying because I've been building a lot lately.

EDIT: I've found that this only occurs in a certain save I have, which is really annoying because everything works fine in my other saves, but the one I've been using recently just doesn't work. This save is one I've been renovating bg houses and using shells with my cc, but I use cc in almost all my saves so I'm really confused as to why it's only this save. I've restarted my computer several times, repaired the game from origin, I've tried to find issues in my cc, but as I said, it's only this save giving me this problem.
