I'm curious:
Are you saying you were standing on the course after ev1 else left, ready to take your stroke, when the WGT message pushed you out?
If so, did you take any shot or was it b4 the first?
What was before?
What happened when the first left? Both at the same time?
Were the rest of you in the lobby, did you click "continue" or the like?
Regarding your question, I'm sorry to say that many have reported that they weren't able to finish MP stroke play when others left. It started with the new lobby.
Your %% will have dropped relentlessly.
