Please help! Cannot see, move or remove doors!

I wish I knew what to tell you. My doors are acting weirdly too. They become locked.. and I can’t unlock them, so my sims are stuck in what ever room they happen to be in. I ended up having to delete all the doors and busting a hole in the wall so they could get out. Have you tried exiting the game? Do you have mods? If not it may be a bug.
