I don't know if this is a new issue or old, but I only recently started experiencing it, and could not find any recent topics about it.
Often when joining an Alternate Shot game, the host / creator of the game does not see all three players filling up the slots, when those of us who joined, do. So we all sit there waiting and of course the host can not tee off!
I may have previously experienced a version of this same bug, when a normal Stroke Play game I created only showed me two other players had joined, but after I clicked Tee Off and got to the game, there were four of us!
Was WGT already aware of this issue? Are you going to fix it anytime soon?
