Jake-The next time(s) you see that would you look at the distance of the ball to the edge of the fringe as best you can. I've been paranoid any time I see the caddie suggest a high scale putt when I know I can use less. Then I get to thinking about this bug a lot of players are yelling about and wind up mind-f'n myself and wind up chipping or flopping.
I did have it happen to me once but I was putting through a lot of fringe (I thought.) That's why I'm wondering if this "bug" is consistent with regards to that distance to the edge. IRL when you're on the edge of the fringe you hit with a certain amount of power. Further back you adjust this and so on. Maybe the game is trying to replicate that. What do you see?
