Bungie, Wanted to let you know that Shiro had a purple triangle over him for a while. There was nothing to pick up from him. I turned in an iron quest (my 5th one according to the record book) and received the bounty for Thorn. The purple triangle went away after I completed the quest and received the gun. I spoke to other players last night who also noticed the same thing. They got the Thorn bounty as well.
