We just finished a Turf War yesterday, and when playing members of our own club, we all got our points posted to the club total, got our XPs posted to the club total, and we all got our coins. I know WGT said this would no longer happen, but it is still happening for us anyway.
However... several of my members got very upset when they would win a head to head match, and got nothing - when the game was over, it did not announce any winner, but instead went straight back to the Main Menu screen, leaving us shorted our entry fee, winnings, and losing a pass.
I did get a reply from WGT that said they cannot do anything about adding coins or points to a person or club during Turf Wars. They did give everyone their missing passes, without question. They acted like the Turf War computer code was something very secretive, and off limits to everyone at WGT except the very special techs. Sounded like a lot of hooey to me, but we just go with the flow.
This has made a lot of our club members leary about playing rounds during Turf Wars, especially in the upper end rooms where losing several hundred thousand coins in entry fees when you win a round really hurts their coin count. Not everyone has millions of coins in their bank.
