Randomly disconnected during Action Sack

Was playing Hockey in Action Sack earlier we were winning 3-1 having already had someone quit on us, then all of a sudden there was a host migration, everyone “quit” then game over with just me in the game get to the credit screen to see “offline credit limit reached” and found I had been booted off XBL, but was able to sign back in straight away…anyone else experienced this?

this is the game with a nice DNF next to my name:
