Bug: Can't go back to boss after disconnect

Just making you aware of an issue I experienced today. Got DC'ed while fighting a map boss. When I logged back in I was in my hideout as expected with all portals still available. When attempting to go back to finish the fight I received an error stating "You cannot rejoin this area after dying." I'm 99% sure I didn't die while DC'ed as my experience didn't change and I lost no portals.
