Hello Nick & Max,
I was not clear in my statement, let me run it twice.
Dealer get the last card out, so the deal is completed. Player 8 is not seated, he gets his hand mucked.
Before first action occurs, it appears that a player who is not at the button, is missing a card.
Missdeal is declared.
Dealer deals again the same hand.
Will player 8 be allowed to play the hand if he is at his seat for the new deal ?
