This 91.37gb "update"

This is ridiculous. I’ve read the crap about changing my external HD settings to stop this and that’s not my problem with it. My problem is that it was updating this in the background for a game of haven’t played in months. I barely noticed that it had been doing this all day after resetting my xbox, my router, and the other devices that use Internet in my household I had no idea it was sucking the bandwidth up and when I found out it was already 80gigs into it. my Internet provider has limits and I have to pay extra if I go over. Thanks for nothing 343, thanks a lot.

Same issue, have not seen any official word on a fix
