Per essence enchantments that are already active on a city are still not properly updating if the amount of essence that city provides is increased.

In the example below the following steps occured:

1. Propaganda was cast, granting +4 gildar from the 2 essence
2. Scrying Pool is completed, granting additional 1 essence
3. Meditation is cast, granting +3 mana from the correct 3 essence
4. Propaganda does NOT yet grant the +6 gildar it should
5. Ended the turn, expecting Propaganda to update
6. New turn and Propaganda still does NOT grant the +6 gildar it should

Had to cancel the current Propaganda enchantment and recast it, wasting the 20 mana casting cost.
