I have not experienced any issues that the OP has.
It did show me how terrible some of my initial reads were on Kiawah.Unlike taking a mulligan and re hitting a putt where the grid dots just went straight up and down rendering it pointless this way you can actually redo the putt and so far not get stiffed for 2 hits.
The thing I didn't like with it was it's active for all players in a friendly skins game(yes there's a timer.It wasn't an issue).Sure there are no credits on the line but this gives all players basically 2 tries for a 1 putt.That just isn't right and isn't the skins games I know.
I haven't tried AS and am hoping it isn't available there for the same reason it shouldn't be available on any MP games
