OK, cards are back in, but a bit more fragile than they were before. There is
no reason to have hundreds of cards in your inventory. The following rules now
apply:
-- you can only carry 25 cards
-- if a pile of cards is left in a non-album container for too long, such as a
room or a bag, they will slowly start to vanish.
Please use albums for the purpose that they were intended. Thank you.
