Hi James,
I've hunted down a few reports of this issue, but I could not confirm anyone who was able to take advantage of the issue. So far it looks like the tee time data we received was initially wrong, but that it was fixed quickly.
Engineering is still looking into these reports, so if you know of any examples where a manager did receive credit for golfers they did not originally start, please let us know. We may need you to write in directly so that we can collect group info, and investigate further.
