I bought this app (the paid version - not the free version) and in the "version updates" it states you can now refresh or restock the store anytime you want. How do l do that? I'm on a Nook HD that has a Nook to Android card installed which gives me Android 4.2. Other than no rain, it seems fine. But some of the reviews at Google play are saying that the room upgrades are not working. I haven't yet tried to buy one so I don't know if that will be a problem for me or not.
