I had a round at SA front 9 yesterday where I hit all greens and got 88% GIR...I drove the 9th green(and stayed on the green) and can only think that this Very Old Bug has come back...thought it was gone :(.
Par threes Do NOT have ANY consequence to fairways in regulation. Never have, Never will! Not even in this screwed up WGT land have they gotten that one wrong...or maybe now...
The only possibility I can think of is that you either drove the 10th and missed the FW or the game counted the 10th Before your drive...or there is a bug ;-)
