Defenders moving out of position

What mode?

Also take a look at instructions and play with different defence depths and player mentalities.

Report back.

I play seasons, I tried different tactics and I can tell you it doesn't make difference. It's not tactics, it's just that this game is rigged.

I play Seasons too. Are you playing a deep line?

Same for me changed defenders changed tactics still same problem either leave to big of a gap or stick to attackers it's inconsistent not sure why 

I play balanced

ya same and i tried pretty much everything,

not mentioning the center back running away for the striker , leaving a huge gap in the center , i have to manualy replace him, so i let go of my cdm who stops coing back... fun huh

It got even worse after the patch, my players are alergic to the ball when deffending.

If this doesn't  get fixed soon, I WANT A REFUND or I'm disliking everything related to this game and writing as many bad reviews as possible

When defending, instead of pressing the tackle button, try holding it for 2-3 seconds, that's what fixed defending from the front for me.
