Stuck in Boss Arena

At steaming springs, and I did a T16 map with +1 to monsters. I was fighting the boss, and I was hanging out around the entrance to the arena when she died. I walked in and grabbed the passive point book, and found myself unable to leave.



I have tried clicking on the "Arena" entrance to leave, however I am stuck behind the thin red well. My theory as to what happened, is that while i was near the entrance to the arena, the game considered me outside the arena while I killed the boss with spark projectiles. So it still considers me outside despite being inside.

Still happening today in Rustbowl map.
