i wondered if someone was going to say the right hand fence.
As that is a boundary fence, there should be no free drop if your near it, but i guess the software isn't good enough to handle obstructions.
while this is in no way correct........
given there should be no free drop, sending you back to the tee for your second shot will allow you to put the ball into a position to reach the green in three. the same would be the probable outcome given a restricted swing/stance from next to the boundary fence.
