When using the Wise Old Woman NPC to decard, she asks you which is more important: 'The item' or 'The cards'.
The choice you make actually makes a difference because selecting 'the item' helps protect your item, whereas selecting 'the cards' helps protect the cards in the item.
If decarding your item happens to fail, there's a chance your item will unforunately be dropped on the floor. This is not a bug. It is part of her script.
So please be very careful when decarding.
