I have a set in this game:

But, no matter which cards I select, I cannot trade. I have also noticed on prior turns, certain sets wouldn't trade, but others would. Something seems screwy there. I will refrain from taking my turn until you chack it out.

If you don't select any is the "Trade Selected Cards" button highlighted/available?

No. I have 3 cards total, they all match. The button is never lit whether I first go to the cards tab, select one card, two cards, all three, none or a combo of 2.

Well this is an easy one :)

Cards B and C have the same image and are both called 'Vlad the Impaler'. i.e. speak to the Designer!

No, they are both called Vlad the Impaler but they are different images. One is the actual Vlad the Impaler and the other is the guy who became the myth of dracula. Does it matter what the names are? If you check the map itself there are 4 separate images.

Card B should be Vlad the Baseball player, C should be the cartoon character guy... At least in one game I have a Card B and the other game I have Card C, with different images.

Ah, so actually in the designer they have the same name but different images.

This is confusing the Player so needs to be changed.

I changed the name of one of the cards so let's see if that matters. Too bad, it was funnier the other way.
