Rapid use can cause Doors to stop Working
I was in the bandits hideout when I decided to use my 9 keys to play with the door. After using up all my keys, the door was closed. I realized I should have kept one to exit. I killed Bera a few times and gathered some more keys, then attempted to open the door multiple times (used multiple keys) and the door did not open. I'm basically stuck until I die now. I also tried relogging, etc.
