POE2 Boss teleported out of the arena and now I'm stuck

My character is stuck in boss arena for Zahmir. He teleported out of the arena using some attack and now I can't portal out as the boss is still alive. His icon is out of the map completely and nothing is happening in the arena itself. Please help I do not want to lose this character.

Same thing happened to me. Zahmir on a map, teleported out and nothing happens :D

Same to me.
