I see. Well hopefully it works out for u but I have my doubts. The quest you are on is generic between all three swords. There is another step after the crucible/major kills to kill an ultra hidden in the dreadnought. When u turn that in, you get another quest that is specific to the sword you have and from the sounds of it, the sword you have on u is what triggers which quest u get. If you have all three, u get all three quests at the same time. If you don't have any, I would suspect it may not trigger the exotic quest at all. The thing that sucks for the op, is that he has one of each and deleted one so without deleting a character to get a new one, he can't get all three.
