I think I encountered a bug, and I can't be sure whether you know of it or not. It has to do with the menu-ing in the camp during exploration, so I'm assuming it will be fixed by the time the new UI stuff is publicly released.
Essentially, Returning to camp from the cooking menu, while having a tier 1 tent, somehow led the game to believe I had a dungeon tent? Or at least I ended up in a dungeon tent screen as if I was using one in a dungeon? I'm really not sure how this could happen.
Kinda obscure and out of the way.
Edit: I might be able to provide a Save file for you to inspect if you need.
