Admittedly the first time I have experienced this but just played a game on Legendary for Squad Battles and was up 7-0 in the 89th minute and the game freezes... waited a good two minutes staring at my frozen players until the game crashes me back to my Xbox game selection screen.
Go back in and yay... I get a 0-3 loss and 0 points. Not super salty about it as the points probably won't matter for my end of week finish but c'mon EA.
You need to at least be able to figure out the difference between a game freeze/crash and someone turning the game off. Oh well... off to sleep - game just keeps getting better.
