Is anyone else's game kicking them back to the dashboard randomly? I was playing NBA 2k14 and it happened 3 times to me now. I've been playing only the quick games just to get into the game. It would randomly go back to the Xbox Home screen and I when I go back into the game it loads from the start as if I just started playing it. This is the only game that has done this to me. I'm testing out my other games to see if maybe the issue is my system (I hope it's just NBA 2k14).
Try a cold reboot by holding down the power button for five seconds.
