Have played two games this morning that on the final hole (#9) on best of par 5's and Merrion, both front 9's, the concede would not work for either player. On the best of par 5's it cost me a game as the other player had to leave with me up 1, he could not concede. Finally ended when both parties agreed to quit. On Merrion I did win but could only do so by putting out. Again, concede would not work for either player. Have not played any other courses so do not know if there are others experiencing the same thing..
