After completing the Zero Hour activity on my Warlock (at the time an alternate character) and which the gun didn’t drop after successful completion (have it on another character), I ABANDONED the quest. I thought I was safe because I’d done the heroic version, too. Now I cannot enter either activity with friends on my Warlock. I went back to Titan to pick the quest back up again and at the table the prompt read “This activity does not interest you.” What do I need to do to be able to pick this quest back up again?
