I can't for some reason add the cards I've purchased from various traders to my caravan deck. It does not appear on the screen when I challenge someone, and in my inventory screen if I try to use them nothing happens. The only thing I appear to be able to do is drop them on the ground, which might be what happens because it just clutters up the misc tab otherwise. If someone has a solution to this or can confirm that it is a bug that would be helpful.

Thanks,
Jaerb

Saw this thread earlier and was really hoping someone could give an answer. I'm having trouble figuring this out as well.

It's bugged. There isn't a patch yet BUT there is a mod that fixes it here...

EDIT:Just noticed this one also you might want, it sorts your new cards better in your inventory
