I've decided to come back and see how Destiny has changed with the new update after a long hiatus from the game to find out if I want to invest in the expansion. Upon logging in I went to the Tower to clear out all of the notifications there and pick up quests etc. However the Speaker has a notification for a quest that I cannot complete. It appears to be the final step of the exotic weapon bounty for Thorn, when I talk to the Speaker in order to complete the quest and claim the Thorn there simply is no reward listed and I am unable to finish it. Before realising this was a bug I had assumed that perhaps I wasn't able to finish the quest as there was already a Thorn in my inventory and figured the game wouldn't allow me to have two at once. So I dismantled the Thorn I had in my inventory thinking that would resolve it, however it hasn't. Attached is a video showing me attempting to hand in the quest and being unable to. I would greatly appreciate any help that will allow me to complete the quest to obtain the reward and remove the notification.
