Sorry to hear about that, JD.
I went to start play of my final round of this Eight Day Showdown, and have encountered what appears to be a game bug.
I chose a sponsor and clicked on 'Play Holes 1-3' button. The game shuffled through a few avatars searching for an opponent, and then suddenly kicked me back to the leaderboard screen with the sponsorship timer counting down, and the 'Play Holes 1-3' button next to it. So I clicked on the play button again, and now I've been on the 'Searching for Opponent' screen for 20+ minutes, with avatar shuffling and no opponent selected.
It doesn't appear that I'll be able to play this final round. :-(
I sent a message to WGT customer service explaining the situation and requesting that at a minimum they credit me back the 1000 cr I spent to enter the Expert tier of this showdown, and also a single ball for the hits I used to advance to the final round. Frustrating for sure, as I would've rather been able to compete for the higher prizes.
