Legendary legacy no loss glitch

This is the 5th-6th time it’s happened. The most recent time is playing a game, 3-3, goes to extra time, I go 4-3 up, then last minute I go 5-3 up. They pause, then I get a connection error notice which kicks me back the the Home Screen, then when I load UT back up, I get a DNF warning and I lose the game 3-0.

over 5 times now! I put a lot of time and stupidly spend money on it, just to be constantly screwed over!
