It seems there's a bug with the inventory card counter and related values. When I'm scanning My Precious the black banner across the bottom is reporting the wrong card counts and value. Even when I'm filtering by set/rarity/color or whatever I have both more cards and more different cards (ie each card of a set) than the banner reports. The list is accurate but the banner is off.
I've also noticed after running offline cache and getting new prices it makes my collection value 0, but the card lists remain accurate. If I go back into each card page and back out it rebuilds the total value :(
*update* sometimes it updates value. More often not.
Hmm, I think I get it. Should be fixed in the next next version.
