There is currently an issue with iOS purchases which may cause your purchase to fail to load into your game despite being charged.
We are working furiously to get this sorted out with Apple.
In the meantime, if you have been double charged for your purchase, please reach out to Apple for a refund. Our apologies, as they do not allow developers to directly process refunds.
Thank you all for your patience and understanding. We will update this announcement when more information becomes available.
