On killing the boss of a Steaming Springs the arena door did not open. Had to relog and enter through original map portal.
After clearing the rest of the map, i visited the boss room again - still with a door that was one way.

Did another Steaming Springs with a boss a short while later - no issues that time.

Same thing happened to me.

Just happened to me as well. Juiced level 11 map too. Tried re-logging as well as restarting the game completely.

I have been havins a similar issue with map bosses. I walk in, kill boss and a red fog gate prevents me from leaving. I had other events to do on map but had to reset it and lose them. It happens with this boss and a few others cant remember what ones.
