So 2 of my buddies and I (Warlock, Hunter and Titan) all have out Siva Engines (Unstable) and have entered in codes using the calculator online to help us. We double check every time to make sure it equals 730 which it does, yet it will not work. Can someone please #help? #Bungie we could really use you on this we've been trying for so long now and really want the weapon we've earned please.
