Right! Expansion permits are a nice "plus" when they occur, but I really enjoy getting a permit with a single tap. Saves a lot of energy I can use for the coin collecting buildings (after comments here about how expensive some storylines are).
I have the Rafflesia Garden and got an Expansion Permit last week from it. Fire Fly Cove usually gives Wisps. Dark Unicorn has only given 1 ticket per drop so far. My White Flygers havent dropped any Expansion Permits yet but I have only had them a few months.
I hope this Pilot, if I can finish her (fingers crossed), gives more Expansion permits!
