ISSUE: 
          At some point in my save, when a city has a Morgawr Governor with SHIP BUILDER skill maxed, ALL naval units costs 0 production, though metal/alloys requirement still exists.


a.) City w/Morgawr Governor (Ship Builder maxed at lvl 2)
Naval unit basic production cost ---> NONE






b.) City with Non-Morgawr Governor or No Governor
Naval Production base cost ---> NON-ZERO
