Champs… (hacker?)

So just went into a game of champs, all 11 of my players had a player indicator above their heads and I couldn’t move a single one of them… the person then proceeds to score two goals then a minute or so later my game lags and it closes down completely and when I loaded it back up it’s obviously come up as a DNF, so I’ve lost of on a champs game and potentially better rewards because of this!!, not the first time I’ve been dnf’d either happened in a rivals match 3-0 up to get the 82+ player pick from the challenge on a flame aswell for double points. The game is so close to never being played again it’s appalling having spent money on this.!
