BANNED for changing game files (.pak)
The grass, bushes and sounds were removed. I got a ban with my friends.

I recommend that you delete all the modified files and check through Steam. Or just re-install the game in order to avoid ban. (If you have not received it yet)

Peace.
We all received it at once anyone who "escaped" that ban wave were literally 10/10 lucky i used it for no less than 5-10 mins for first time instant ban shame... I was actually having stable fps and a good start =')
