Apparently an MP strokeplay game with three players first, then reduced to two.
And, in the "Release Notes" thread, the pop-up has been shown which offers to quit the game when "behind":
Me thinks it has been fooled here, in strokeplay, by the well-known wrong inclusion of the player who has quitted before. Apparently that fault hasn't been fixed yet, so he will be shown as the "winner" at the end because he has less strokes than anybody else due to playing less holes, and he might well be up with a significant margin, thus the withdrawal offer to those who are still in the game.
Me thinks this pop-up is meant to lead players into the "right" direction of quitting, but it ended up as just another badly executed thought...
