EA Meltdown!

Something strange is happening and over the last couple of days the game is doing weird things! My players keep changing positions and I only realise when I try go change tactics mid game and they have moved positions. The buttons I've used all the time to tackle are now just getting me constant yellow cards. I am now being called offside about 8 - 10 times a game with the same team and settings (I swear most of the decisions are also wrong). I've gone from Division 2 down to Division 8 in a heartbeat, and I'm suddenly losing 10 times more than I now win! I notice a lot of players that beat me seem to have faster teams, tackle like a knife through butter, tackle from behind as they smash into my players, and actually knock them over in the process! My players are all over the place and no matter what I do (and I'm aware of game settings and player set ups) my team are now always too high and other teams are constantly running into yards of open space behind my defenders. I can play one game and the ball pings around fast and easy but the next 10 games the ball feels like it's made of iron! I am also noticing players in both the lower and higher devious with immaculate win records that take them straight to Div 3, etc, without even going down once or losing a single game (and I have PC players turned off) If EA think for a second I will ever buy another EA football game then they're frigging mad!!
