Once you have everything set up and have purchased a proof, how easy is it to change the design of a card or two, or your tuck box design? I need to do some tweaking.
Is it possible to change these once you have the deck published?
To make any changes to your game, you'll first need to unpublish it. You can then make the changes and republish your game (there's no need to reorder the new version before publishing).
