Confused about Commercial and Industrios

[ColoradoBBQ]

In the Civilization dictionary, it explains that industrious and commercial gets an extra bonus to their fields for cities and metropolis. I'm playing the Mayas and I have two size 9 cities in the ancient ages but they don't seem to get this extra shield in the city center. Am I missing something here or this only applies to metropolis.

Dunno 'bout Conquests, but in PTW if the base square produces 0 shields (eg: non- bonus grassland), it will give you 1 shield instead for Town size settlements, but the latter case will not see a second shield for Industrious attribute when the settlement grows to City size, and IIRC will have a total of 2 shields once it gets to Metropolis size.

Maybe the Despotism penalty is in effect (change to a better government).
