Currently i am realy confused because the citys shows weird stuff in theyr head up display. Like i have 1 goldmine linked to the city and the city itself says +1 gold? The same with all other ressources, it just shows 1,1,1,1 from the standard buildings and not the real resources. It realy makes management a pain, i stoped playing after i had 4 citys because i could just not figure out which city needs what improvements to be usefully.

If the city would display the right values like +5 gold if it has a goldmine than i would know to build a market there etc

Other things i noticed:

Building shrines on shards wont give the +20% essence bonus, i had 3 shrines and my soverign still had 18 essence (the same as before i build the 3 shrines).
