was just doing master conquest derealize, got to the final boss with 0 revives due to the timer running out (i think needs increasing too but that's a seperate matter), got to the last third of both health bars, killed the not-taken one and instead of the door opening to allow us to finish, it did nothing of the sort and we were soft-locked. one of my teammates did die but i'm not sure if this contributed to the soft-lock.
