There's a ghost in the lunar complex that I can't pick up because it isn't there. The dark room where you can fight the Hand of Crota, along the right wall, on top of a box. I don't have the Grimoire Card, I believe it's Darkness 3, but the Ghost just isn't there. Also, I've killed Omnigul 3 times. Still don't have her Grimoire Card.
