I have run the nightfall close to 20 times now and still no ghost.(I love the nightfall but this is ridiculous) Now however I am getting serious levels of lag. I always blackscreen at the tower, I keep getting kicked from parties, and it takes a minute to dismantle anything. On top of that I keep getting messages saying "error code rabbit" and I get kicked to orbit. I have even been kicked from the game with the message that I can't access the servers anymore. I have only played for a total of 6 hours this week so far trying to get that ghost. Is it possible to play the game too much? Isn't there a increased chance at the reward after not getting it? I really want the ghost.
