I posted this already and someone had said it was working, try waiting a turn, but it is not working. I just tried it out in game to be sure and waited several turns and both Nature's bounty and Sovereigns call did not update. Screenshot below.
City started with 2 Essence, cast both Sovereign's call and nature's bounty. Build a scrying pool, now have 3 essence but still only getting a bonus of 2 to grain. I waited several turns already, no change.
