The only times I`ve experienced anything coming close to the stance/lie affecting the ball flight have been on Oakmont, and it`s always been when the ball is on a side slope of a bunker in deep 30 or 40% rough.
These may have been "bugs" or WGT toying (testing) with the idea of including this affect .I still see this from time to time but not as much as when Oak was first released...I`ve learned to avoid being in these positions as much as I used to be when learning the course ;-).
I still have a replay on my profile page showing the worst of these. It was in my US Open round last year on #14. 92yds to the pin with a 13mph tailwind, I think I used a 115yd pitching wedge almost full power with half backspin and I left the aiming arrow directly on the pin. I dinged it and watched it squirt out to the right almost perpendicular to the line, and then it took another turn back toward the pin when it hit the fairway as if it hit a stone or something.
As I said, it may be "bugs" rather than the proper affect, but I still see these "unexpected outcomes" occasionally on Oak when it`s on the bunkers slope in the rough. I have no clue to posting a link here, just check out the replay on my profile. It`s good for a laugh if nothing else :-D
