Hi WGTers !
Similar thing happened to me ...
After a drive on hole 18 the ball stopped on cart path, and I got a message Immovable obstruction, free drop, but I was back at tee again.
Then I choose to watch a replay and recorded it, I exit the replay and then I am where the free drop should be, not at the tee again.
So if you ever happen to end up on that cart path, and the game brings you back on the tee, watch a replay first then exit and play your second shot from a free drop a foot or two before the cart path.
Here is a video of the replay. You can't see me back on tee, because I recorded only after I started replay. I can't screencast while playing, because of my computer performance. If I start recording while playing, when I swing, the swing meter goes skipping like crazy.
