Unplayable game after the update

I have this situation in fc mobile. I notice the A.i is for reason able to send defenders straight into the opposing team goal square, but as I don't use auto my defenders are still in the midfield while their Strikers are miles in front leaving Goalie unattended, so my defenders go into flash gear to catch up and make an attempt as blocking.  But when a player disconnects from the game thier A.I become ametur weak or freeze, great for me keep playing. I also think my team looses all it skill in H2H matches, but plays awesome in Ai matches.  I think its just H2h matches that the game is messed up.
