I was doing the quest "A Sandy Scandal", and when I got to the vault, it was already opened and there were no buttons on the keypad to get in. It told me to report back to the guard once I went into the already opened vault, but when I try to get out, it tells me I shouldn't leave until I'm done inspecting the vault. My questbook still tells me to put the code into the vault, but I can't do that, as there are no buttons. I've tried relogging, going onto other lobbies, and switching versions. I'm currently in 1.12. I also can't post pictures, it tells me I need to have at least 10 forum posts in order to do that.
