No Picnic Achievement
Sink a 40ft putt with Green Grid Beads turned OFF
This is actually much easier than it sounds as you can manipulate the game settings mid-round after every shot. On any large green play to 40ft(12.2m) away from the pin (St Andrew's has plenty of huge greens if you can't find one easily), and line up your putt using the putt preview to ensure it is going in. Once lined up, press start and enter the gameplay settings menu, turn the green grid off and resume the game. Sink the putt and the achievement unlocks.
