To all players who suffered a loss when the opponent cheats - the game freeze and you get a loss because you dont have patience. Here is the secret - PATIENCE.
By my experience the cheat deactivates after 60-70 minutes, but most cheaters dont have patience and the game continue after 20 minutes.
I confirmed this with several cheaters trying this on me, I waited and figured it out. The game freezes for you and him. Check their seasons history, If they have lots of 0-3 wins, they cheat and you should report them. Have patience and the game will continue, cheaters have no skill, you will most likely win the match. I hope this will help for you all
