Stuck in steaming springs map boss arena

Bug Report ID: #1639062917

After killing the boss in Steaming Springs map the barrier preventing exiting the arena did not go away so I could not go complete the rest of my map.

Have same problem just now. Saw someone else with the same issue (https://www.pathofexile.com/forum/view-thread/3611682)

The problem is it blocks the progression on the atlas.

Got it too. Used "Ligthning Warp" to cull the boss. The barrier did not disappear.

EDIT: However, I could "Exit to Character Selection", log back in, enter the map again and finish the rest of the map (all rares) and complete the map nevertheless.

I am having the same issue. The boss vanishes into the ground at around 30-40% hp and never comes back. The arena is locked, i cant leave, and the boss does not reappear.
