I have been having consistent errors with remaining in story missions if I'm part of a fireteam with friends. I keep getting kicked with various errors. GOPHER, JELLYFISH, FLY, CATTLE, VULTURE, all at different times. I have my system plugged directly into my router and I've got Fios, so I doubt it's my connection speed,and I have a moderate NAT. Plus, I remain connected to XBL and in a party without interruption throughout. The friends I'm trying to play with are playing the game off a disc and have no connection issues at all, which is why I'm not sure if it's something to do with playing a digital version of the game. I've tried a hard reset of my system, resetting my router, I don't know if deleting and re-installing the game will make any kind of difference. It sucks though, I get kicked 10-15 times per hour at least if I try to join a friends fireteam and it's making the game nearly unplayable. Any suggestions or help would be much appreciated.
