Since add-ons don't typically involve seating or reseating a player, receipts for add-ons don't include seating information. They probably should. Rebuys can be tricky, too, because of the flow involved in rebuying a player. Seating of a player who is rebuying after the player busted out of the tournament doesn't happen until after the receipt is generated, which means the receipt won't have the player's seating assignment. Rebuys where the player wasn't busted out or where the rebuy occurs at time of bust-out (when the application asks if the player wants to rebuy in order to retain their current seat) will have seating information. I'll make a note to revisit this.
