I can confirm what Infinito is saying. While playing a practice round, I intentionally putted up to where I thought the problem was based upon Infinito's description of 16ft away and 11 inches above the hole. I found it. Infinito's calculation of the power needed to get the ball to the hole from the fringe is spot on. So I tried it, Redwood Putter, 15 foot scale, half way back equals a 7.5 ft putt. It didn't move like he says. Confirmed I was on the fringe.
Took a screen shot and reported the bug to WGT. Here's the spot to beware of.
I tried the 30 ft scale, same power, it also didn't move. It eventually did move off the fringe using the 45ft scale, same power. But I can't be sure the prior two attempts didn't move the ball the needed inches to get it off the "dead spot" on the fringe.
I then restarted and played practice to the 13th again. Lo and behold, borntobesting is also correct saying there is fairway up there. A little further from the hole there is fairway. Here's a picture of that spot showing it says fairway and the distance is in yards(upper right) not feet.

The bottom line for all of us is, if you are in this position on KI #13, chip it, don't try to putt it.
