this has happened to me, i submitted a report and never had a response.
How are you supposed to know if this is going to happen? Does it only happen on certain holes? If so can wgt provide a list. Should we use flop all the time from the fringe just to be sure, 9 out of 10 times putting from the fringe is fine, so why does this happen? It was BP #6 back left where it happened for me, during a paid for tournament.
