Elite Legion T3 Room bricked

Bug report reference 571,634,589

second time this has happend to me. Running a T3 legion barracks, and it cannot be completed.

I think i kill all the enemies before they can kill the scorpion but now the room cannot be completed, i am force to portal out of the temple and walk back in.

kind of annoying but should be avoidable if don't kill so fast.

How did you get out, I cant portal out from the room, I'm completely stuck.
