OK so when you got the Epic farmyard are all production slots open? Are all production types available? I know you need to run the chain over and over again to get unlocks, but how do the unlocks work? You start with water slot only and each chain gives another unlock? Or you start with all and each chain unlocks level upgrade?
I wish people would put a bit more info into this except "Completion of each chain grants another unlock" I have no idea what that means...Unlocks another type of production in the yard or another level of all available production?
