Invisible cards bug

[Taffer]

I played against Level 5 (Aethiel). I had 2 Electrum Hourglasses in play and sometimes an additional Sundial, too. Once I noticed that though I had only 4-5 cards, hasten did not work (clicking sound but no new card). That lasted for a few turns when finally after my turn the game forced me to discard a card (with 6 cards in my hand). In that moment a thin white frame appeared at the bottom slots as if they had been some invisible cards.

It was an annoying bug but at least finally I won with Elemental Mastery

This happens sometimes when you use the hasten ability too fast. Wait for the card drawing animation to finish and this will never happen. On a related note, never use any kind of Shard immediately after hastening (while the card draw animation is going) or the card you draw from hasten will disappear before it hits your hand.
