I'm the Guildmaster of the Thieve's Guild and suddenly Honningbrew Meadery is locked. I even tried going back through the tunnels under it from the boilery, since I still had the key. Mallus shouts at me to get out or he'll call the guard. It's about noon, so it's not that it's a time that normally closed. How can I get it to open again? I'd really like to sell stuff to Mallus.....
