I did the Ghorn quest and the final mission. It popped up that I "received" it, but my inventory was full. Thought, no biggy. Finished the mission and went to see the Postmaster, no Gally. I did the mission again. Still nothing. The quest is gone, Saladin praised me, it's not in my blueprints and I still can't use my Iron Ghorn. Please fix this. This is extremely upsetting and it's not fair that some of us who did the quest and the work don't get to use one of the most powerful and iconic weapons.
same thing happened to me. I know this has happened to several people but it be nice if bungie would acknowledge the issue and let me know if I will be able to get my earned ghorn at a later date somehow.
