I have made changes and I am in the process of testing them. One of them was regarding the water on the 12th hole. Here is the golf rule.
"When you hit into any water hazard, you always have the option of trying to hit the ball out of that hazard. If the ball is inside the margin of a hazard but not actually in water, that might be feasible. If the ball is in water, then you'll almost certainly assess yourself a 1-stroke penalty and drop a new ball outside the hazard.
Whilst the ball might be in the middle of the lake technically you still have that option although in real life that would not be possible. I guess the person playing the game will just have to make the moral right choice"
