I killed the oppressive mind in its second phase and the mission did not end. A few enemies spawned, but the nodes protecting the mind did not. I am left in the final boss room, alone, with the message "defeat the oppressive mind" (which I did) The mind was at 1 1/2 bars of health after the first phase and then I thundercrash/falling star supered and killed him in the second phase. Now I have to quit the mission without being able to complete it.
