The below screen snapshot shows the properties of the Nephelinite command ship.  Under "Special Abilities" it says "Fully heals the fleet.".  However, it appears that it only fully heals itself, not the other ships in the fleet.  The first screen snapshot also shows that the hit points of the Nephelinite ship are full, but the second and third screen snapshots show that the other 2 ships in the fleet are not fully healed.

Do I not understand what "Fully heals the fleet." means or is this a bug?
