I didn't get this new goal today either.... I'm level 37 but don't have Kaz walking around yet (which I think takes faery bridge to trigger?). Looks like you would also need the ability to make allergy potions (that's locked by goal for me - haven't looked on the hub to figure out what goal triggers it) and also looks like you'd need a faery workshop in order to make the faery paste. (I know those faery workshops were released before the recent return of Kaz, but not sure if they are sequential or if they were just chronological)
