Ahhh I think you have it mixed up a little.
The new $40 tier is a full pledge on its own. IT's not an add-on. This way, people can grab the $40 tier with JUST the cards, in case they didn't want the dice.
You added $30 on for an add-on of the 126-card deck. That's just fine, and it's not gone! You can still see it in the Add-Ons section of the project.
Thanks! : )
