I have collected all 18 ghosts but I’m only able to place 17 at the Ghost’s House at the Tharsis Spaceport. I really enjoy playing Destiny but I’m really frustrated by this bug. I am 21 of 22 Triumphs to obtain the Renegades title. As a novice gamer this is really disheartening as some of the challenges require time, patience and hard work. And what’s worse is, I have completed several of the hardest triumphs such as Highest Risk, Highest Reward. Thanks for your attention to this matter.
