Tell me about it, I had a great front nine for me at -7 - didn't make a birdie on the way home! Purely my doing. its a course I don't know and virtually every putt on the way home was at least 3 inches downhill.
A couple of putts that I could not read including a 5 foot putt (no elevation change) that I really had no idea of where it would break to or if there was any break - missed the line by at least a foot lol. Tough greens. I can't and won't speak for Goldeena, but my focus over 18 seems to wander too, for me the old grey matter seems to go AWOL, heck at this rate I may have to split my games into the 3 hole duration!
