As the title suggests, I completed the non-challenge mode run for Crota's End during contest mode but upon interacting with the sword/vendor at the end of the raid, I did not receive the quest for Necrochasm unlike the rest of my fireteam that did. I was told that the quest is guaranteed and for the first 48 hours it would give you the gun, but I did not receive either. Was wondering if anyone else has had this experience and if it's likely to be solved, really bummed I was the only one not to receive the gun at the end...
