On hole 14 there is a small world hole in both of the pipes.
On hole 11 you come just short of getting the hole in one. (You used to be able to get the hole in one all the time but now you come just short most of the time)
On hole 17 the laser walls seem to be missing the square block on either side of some of them.
On hole 15 there is a small collision error on this wall where you bounce off nothing.
