Minor patch

This patch fixes a bug that prevented players from delivering medium cargo while unloading, and a bug that prevented fish farms from working after loading a savegame.

• Tuned fuel consumption on all boats
  
• Fixed issue where fish farms would not consume food or grow after loading a savegame.
  
• Fixed a bug where medium cargo would not register correctly when unloaded
  

Thank you for your support and patience.
