THIS is why you don't attempt to reach the 9th at OAK in two... this was a 7-iron, by the way....

At the end of the shot I got a message 'immovable obstruction- free drop' (I assume that would be the big building it hit)- except the 'free drop' was back in the fairway where the initial shot was hit. So, stroke-and-distance penalty.. no 'free drop'. And since it's an RG, it's a W/D for me. This will be going in the 'bug' forum.
