I too just lost 6 balls at Merion on hole 2. my tee shot ended up in the rough at the base of the trees on the right hand side. I couldn't even see the ball. hitting it in several different directions resulted in a lost ball with my last shot reaching the maximum number of shots. 5 balls were ones I had paid for and number 6 was one of the unlimited balls.
I think this game is a con as far as balls being lost is concerned. I know this isn't real golf but in a real round of golf, if you hit the ball in the rough or long grass and the ball hardly moves an inch, it certainly wouldn't be lost. you could simply pick it up and take a drop. but it seems with this game that the slightest thing is enough to consider a ball lost.
Stop ripping us off WGT. it's a good way to lose players and money. surely you must see this.
