If I have one gold and one plain copy of a card, the Collection Tracker will say I only own 1 copy of the card.
Can we fix this?
Most people just care about whether they have two of every card, and one of every legendary, that they want to own. People who care about golden cards are usually trying to build a full golden collection. That's how the Hearthstone game itself works -- by default, you see both golden and non-golden in your collection, unless you hit Crafting -> Show only golden cards. The Collection Tracker doesn't do it that way.
