So, Gumroad said all files would still be available to users when we removed our projects-- which turned out to not be true!
That said, I've also made several posts about how folks should reach out to me if they don't have access to their files so, if that happened to you (which it sounds like it has) please contact me at darkchibishadow @ gmail . com with your receipts and I'll make sure you get everything that's been removed from Gumroad.
In the future, I'd consider trying to find a way to contact artists directly (my info is on my website) before making a post on an unrelated product-- it's usually a much faster way to fix the problem!
