it has only been posted by a player that they were told in a support ticket that it is a bug. Dawn has not confirmed that it is a big. In fact Dawn's response in a previous thread suggested that getting more then 3 sails a day is not an issue to the dev team. Basically he responded to someone saying that they didnt like getting sunk even more by the same guild so they could get in their extra sails was fair. Dawn's response was THAT IS WHY WE CHANGED IT SO YOU GET HALF REWARDS JUST FOR SAILING. So to me that means we may get our extra sails back.
