This glitch should had been fixed long time ago, so if even everyone but you quits you can finish the game alone. If wgt claims that it is the most realistic game of golf better make one.
In real life you would finish the game regardless of quitters.
I have already mention this problem in my post:

I have written several e-mails to wgt in the past and got the same solutions from wgt as some players have advised here: join the CC and play with trusted players.
This might work for some but not everyone here it just shows you laziness of wgt.
