Fraenkel: Had a couple of them on hole 16 at Merion
Happened to me as well. Both times I played it in the last month. The approach shot wouldn't load. Same thing with the tee shot on #13 on Pinehurst. What did the trick for me was to log out, go to my neighbour (luckily a friendly one), logged on, played the shot (which miraculously loaded there), then continued without interruptions from home.
Edit.: Hopefully I'll get a 2nd computer soon, so I won't have to consider, if my neighbour is at home and awake, before I play my round on these courses ;-)
