Trial of The Nurturer can be accomplished by watering trees。
Well I expanded to the space others did and no badge. It allowed me to exand and it unlocked as usual, but nothing else. Tried to reset game and still no badge.
I've deleted and reinstalled it again and still no badge for expanding.
i wished i had made extra expansion permits before i did the last expansion that needed one... because after you have done that, the option disappears in the royal exchange, and i think we will need them after a next update... so think about it, before you decide to use it immediately, the expansion wi the permit does not unlock someting like i thought when i rushed to use my permit!
