I have 50/50 Tributes placed in the Tribute Hall but I cannot place the 51st Tribute in the left side of the front door or unlock the Triumph Gotta Collect 'Em All. I found this video with someone else who has the same issue https://www.youtube.com/watch?v=x2wt8HBeC10 Is this bugged? From googling it looks like there is other players have had the same issue but I haven't found a response on these forums from Bungie or a moderator regarding the issue.
