When I started on PC, I deleted the Rat King Quest because the gun was worthless and it's operation was useless and impractical. So now it's being revamped, I went to try to get the quest item again, and it's not available like the Mida quest item or Drang etc. So then I found a work around where you do the mission with someone who has it the first time, and you get it at the end. My primary slot filled with blue loot and I did not get the quest item and it's not in the postmaster. Come on Bungie.
