So, I insult people who insult me first, and I'm the douche.
Gotcha.
I should have known not to ask on a forum.
They are always full of people who don't read the posts properly.
Not one single person has addressed the 2 points of 1) I have played this formation since I started the game, with no problems.
2) The percentage rate of possession went straight to 80% and did not move from that for the entire match. No deviation, nothing. Whic is impossible unless the player has manipulated it.
