I’ve been working with decks trying to get something to work and ran across this issue. Maybe it’s already been fixed and maybe not. But sending a cards from one deck to another reverses the order of the deck/stack. I would think this is a bug…but maybe not. Maybe there should be an option to preserve order when sending a deck?
