Hello, i have recently bought StoneHearth + Beta thinking i would get it instantly, not in December i am really hoping i can get a refund
Sorry to hear that … you sure you don’t just wanna wait a few months?
If you do want a refund email: contact@radiant-entertainment.com with all your information and they’ll be able to sort you out 
for future reference, refunds for pledges made through the humble bundle link should be taken up directly with humble bundle… we’re not entirely sure of the options HB will provide, but they should be able to address a refund request…
hope that helps!
