I'm sick and tired of being forfeited by WGT - last 5 games it's forfeited me 4 times - drawing in one, winning in the other three. What a farce, I'm so frustrated!
you're probably getting game invites and not declining them.
if you get an invite and you don't decline it then you will forfeit. it's a known bug for over a year.
solution Turn off visibility when playing.
