this game sucks sometimes
Yes it does and sometimes it is awesome.
FYI: There are many threads you can search which people have experienced getting penalized when their opponent quits/forfeits in the middle of the match. You can search them using the search box to the right side of the screen, use the word "forfeits".
This has been a "glitch" for some time. When I am playing in the showdowns, and a player forfeits, I immediately close the game window and reload. It seems to have worked for me, so far.
WGT can be frustrating at times, to say the least but it still a great game.
