I've been trying every way possibly to fix this quest I have deleted it on all characters and reacquired it and still cant get the exotic memento that Petra gives. I have not been able to get this exotic which this goes against bungie the entire point of the game is that it is a looter shooter with quests getting exotics, legendries more and when you cant even get the one exotic that is the most covetited weapon and the strongest bow in the game if this is not fixed then me and the many people I know with this same problem are leaving Bungie this better get FIXED!!!
