I have suffered this problem for years on road trips and have found a temporary solution (but if the devs could fix it entirely that would be great). So in my experience, it is quite random how long it takes to crash. Sometimes a few minutes, sometimes a few seconds. I've figured out that if you sign out of XBox live before a planned time without internet, the game does fine. It's like it attempts to connect even without WiFi, but without the WiFi, it is unsuccessful and tries again. Over and over until the game freezes and you have to restart it. It seems to affect many versions – 1.7, possibly older, through 1.9. I have not been able to test it in 1.10 yet. Let me know if anyone else can fix it in the same way.
