The same happened to me. I played today at 01:30 am (GMT time). I was winning 1-0 at half time. I have just substituted a player with a yellow card. At about 50 min, the game crashed. I could rejoin just about 5 minutes later. The match has already finished and it was "different". In the new version of the match, I lost 1-0 at half time and my player didnt get any yellow card. At least I have won 4-2.
