I just hit on into the lake and it took my ball and so I hit mulligan and I didnt get my ball back....
Just -2 on the very next ball...
You shouldn't get the ball back. In real life if you take a mulligan on a lost ball you still lose the ball. It doesn't magically reappear.
The -2 is really poor on WGT's part though. Ball life should only be charged one hit for each time a club actually strikes the ball. No more than that.
