I've had this problem for a while, but it seems to still be happening. When I load a tournament, if I load the leaderboard once play begins, the game crashes. No error...it just hangs. It usually happens if I load the leaderboard right after I start the tourney or closest to the pin challenge. So, I've learned to wait until the end of the round to see the leaderboard or look at it from the main web page and not from the game.
I have had it work sometimes in the middle of the round.
