Bonuses from enchantments that scale off essence or shards do not update after casting.
- If I build a scrying pool on a 2-essence city that has Inspiration, Inspiration should update to grant 3 research/season
- [this is a separate bug] If I get a life shard, regeneration should automatically give more healing.
Currently in both cases I would have to dispel and re-cast the spell
Edit: It looks like regeneration was a separate issue, only city enchantments are bugged when essence is updated.
