That doesn't help when you die in the room and it respawns you in the next room after that puzzle. That is what makes this mission impossible to pass if you fail that part and like you Devs usually say to drop a bugged mission and pick it up from the list again, this mission punishes you for dropping it due to this bug with its cooldown so now we miss out of the DOFF and Vulcan Lirpa rewards and cannot try to run this till it appears again on September 13, 2013.

That doesn't help after the fact for anyone thats had this issue since you can't repeat the mission after you respawn in the room after the puzzle when you die and drop it due to this bug.
