Stuck in boss arena in Rustbowl map

Bug Report ID: #2225262506
Location: Rustbowl map

After defeating the boss (rather quickly), I am trapped in the boss room by a red wall. I see two doors on my map with an "Arena" label hovering over them, but they appear to only be accessible from the exterior of the arena. By going to character select and loading back into my hideout, I was able to re-enter the map at the default portal (thankfully, I hadn't opened another portal to overwrite its position to the boss arena).

Just had this happen as well. Can't exit
