Thanks for the support everyone, I'm happy (even though it's sad) to see that I'm not the only one in this situation.
In my case it wouldn't be too troublesome to copy-paste everything since it was only me doing the study, with some comments being added here and there.
Obsydian, I'm really glad you offered it! I saw the deck study section on TTM, but I was too shy to ask huhu. I'm really glad to know you would be happy to accept a deck study of the Mystical Cats Tarot
With the shutting down of AT I don't have time to resume it now anyway (need to save a lot of things!) but I'll gladly PM you on TTM when I'll be ready
Thanks again ♡
