I own the adventures, although I unfortunately dusted the cards (poor choice in hindsight). I am on their website is giving me the option to "buy now". I don't want to do that though in the risk I will be charged $32 Australian dollars just to be able to access adventures I already have, without actually receiving any of the cards.

Has there been any official confirmation?

Thank You!!!

I didn't find the right solution from the Internet.
