Today when I went to the tower I noticed a ghost in mid air. At first I thought it might be another guardians ghost who hadn't loaded in, but then it rose up and floated up over the side of the tower and down off the edge. Then later when I did the same thing with a different character and saw it again. I thought this was cool. Has anyone else seen this? Unless I'm being a massive noob about this, I have not seen anything else about this guardianless ghost.
