Castaways

Summary

Players will now have a chance to encounter Castaways while at sea
Castaways are NPCs that will occasionally spawn on Fishing Spots and on NPC Ships
Each Castaway has a target Town destination they must to be returned to

Players can accept a Castaway onto their ship by approaching within 8 tiles of it and using the "Accept Escort" shift-click menu option or saying "I will take thee"
Players can accept Castaways from an another player's ship if that ship is unoccupied or the player is considered friendly to that ship

To rescue a Castaway, players must sail them to the Town listed for the NPC which is displayed on single-click
A rescue is completed if the NPC enters the Guard Zone of the listed town, or the player double-clicks a Dockmaster within the Town
The Guard Zone in some coastal towns do not extend far into the ocean, so the player should use a Dockmaster in these locations (each town should have several reachable)
When a player successfully rescues a Castaway, a random Ship Upgrade or Crewmember Contract added into their ship's Pending Salvage

Players can have at most 2 Castaways on board their ship at a time
Players will not be able to accept a Castaway on a Ship if any hostile creatures are present on the ship

Players can Abandon a Castaway by shift-clicking and selecting the "Abandon Escort" menu option
Abandoning a Castaway will delete the NPC
If a ship ever sinks or docks, all Castaways on board the ship will automatically be treated as being Abandoned (deleted)
