This happened to me on 16 Kiawah. Went to hit my 3rd shot from 58 yards from the second cut of rough and I got an unexpected error and the game shut down right as I made impact. So I refreshed my browser and it came back. What it came back to was a 60 yard shot from the FIRST cut of rough.
Now, while i went on to make birdie, it may not have affected my score as I did get up and down from a similar distance from the second cut to save par on 15. However, if there are changes in position after disconnects, could this be exploited by those who end up stymied behind a tree?
