I'm on Xbox with the same issue. I managed to get a rare bounty to drop on my main character (the one with the quest active)...but the rare bounty that dropped was the one that requires completing 12 daily forge bounties and 1 weekly dorge bounty... unfortunately I have already completed both of the weekly bounties this week on this character...so now I'm locked out. I deleted the uncompleteable rare bounty in the hope that I can get another to drop before reset...this sucks! Hhheeelllppp Bungie!
