It's not just you, it's everyone (I assume) since I'm experiencing it as well. Really annoying, and just like you, I have been losing and drawing ever since the update, after having a 8 game win-streak with 2 goals conceded, so I do think it affects the gameplay and isn't just a visual bug - mainly because I like to put all my defenders at "backwards arrow" aka. defensive mode, but every time I watch the live play I see my defenders push up the pitch like crazy.

This needs to be fixed ASAP, hope the developers are aware of this.
