So there I was, using /autofollow to follow another character as she swam in an underwater tunnel near the giant mushroom guy and all of the sudden I'm no longer in the water, but out of bounds in the world. I have no idea what the location is (who even spams /loc like that), but there's some gap in the world where it's possible to swim through and get outside the map. So that's fun.
Nope. She was stuck out of the world and sinking (she had levitate on). /rewind did not work and I had to Throne (or gate, or stein, whatever) out.
