Boss arena bug. Can't leave arena.

same here cant leave steaming spring arena after killing boss

Same, stuck in boss arena and can't finish the map.
Reference number 4,022,492,485

I had this today aswell. I cleared the whole map with delirium fog but did not pick up much loot and did not do breech that was also on the map, I was planning to do that after I was done with the delirium. I entered boss arena and killed the boss and then I could not go back to pick up my loot and do the breech. That was quite sucky..

Edit: I am again stuck in a boss arena and its not a delirium map. Map is not complete, killed the boss and can't get out. What I noticed is that both times there was no "door" to enter the arena, but there is now after killing the boss.

Also got stuck after defeating boss and door appearing to exit when there was no door to enter boss area.

Just got stuck on this one myself:
Bug Report ID: #1743498811
Map: Rustbowl; boss defeated wont let me out; tried to portal out and come back to reset but stuck.
Only 1 rare remained but i cant get to it.

Just hit escape and relog, you will be spawned back into your hide out. Just enter and you will be back at your first portal? Hardcore people uses this to safe their butts, so use it.
