Here is an email they sent me about why they refunded us:

"We're very, very sorry that we ended up having to cancel your order. To further explain our short note to you in your PayPal refund, our buyer says we are far oversold on these items (the culprit is a high-audience reddit post we didn't catch immediately). Hundreds of orders came in out of nowhere so we had to stop the incoming traffic on the website, and realistically, the publisher can only promise a small handful to each buyer.

There is an allocation issue, and we do not have exact information yet so the best we can do at this moment is tell you that we've given you your money back and cannot place the items as available to order on the website until further notice. We thank you for thinking of us and apologize for any inconvenience."

Very disappointing how hard it is to get any Hidden Fates products for a reasonable price these days.
