|Release date||10 October 2016 (Update)|
The message in a bottle to locate these castaways was last visible 3 days ago on 13 August. It will be visible again in 3 days on 19 August. (wrong?) Once a message in a bottle is found and when a player has walked near its spawn location when it was visible it will always be visible, unless the message in the bottle or its treasure map is in the player's bank or inventory.
