Siren head in Torgues dlc is not popping in any machines. I have played this dlc in and out and have checked literally hundreds of times for the Sirens head; yet all I get is Commando and Mechromancer constantly. I have never even seen Zerker or Assassin either. I have a slew of legendaries and seraph items if anyone can help me with this issue. Message me on live and thanks ahead of time. You stay classy Gamefaqs.
