Can you figure it out and re-enable selling it on itch? I do not trust my email address to keep game key safe, I'd much rather had an itch io account that stores my purchase.I've bought it here twice, year ago, and I want to buy it again as a gift.
That's entirely on Itch.io at this point I think.
Itch.io themselves haven't paid the dev in months. If you want to buy it for someone else, get it for them through Vintage Story's website.
buy the game through their official website
I did already
