I think Bollux and JakeS have commented (ranted :)) about it but I believe them.
One of the holes dis-(cussed ;)) was Beth #10 from behind the back left pin placement. I had a replay on my profile that showed an obvious mapping issue without a doubt. I was well off the green, a yd or more so no putting option, and tried a chip... I dinged it and watched it bobble what appeared to be 6inches up and down...right at the fringe/green boundary. The bobbling effectively killed any chance of it rolling normally onto the green and towards the hole. I reported it in-game and saved it ...`til this morning, of coarse :).
I also had one on KI #18 green showing the same mapping issue just left and 3-4yds short of pin high. My approach was going right at the hole and hit this black-hole of fringe where it dropped and jumped...again, right on the fringe/green line and stopped dead. My next shot was doomed before I even hit it :(. I also reported in-game on that one...for all the good it`ll do. I`ve avoided both places successfully since ;-).
KI #13 was another one. Back left of the pin on the fringe or further is "no-mans land", just try to avoid it.
