Bungie removed the Last Wish challenge bounty from Hawthorne in a stealthy way. The 2nd piece of loot does drop from completing the challenge but the challenge failed text never appear once. I remember before Bungie shadowpatched the Last Wish challenge bounty, that the challenge failed text would only show up when you acquire said bounty from Hawthorne, so this could be an unintentional side effect of removing Last Wish challenge bounty, can someone at Bungie take a look at this?
