Obstagoon Wicked Ruler ability Bug

Hey,

I was using the Wicker Ruler ability which makes opponent discard cards until they have 4 left in their hand.

I accidentally clicked on the ability while the opponent already had only 4 cards in their hand, and it seemed to just bug out. I wasn't able to do anything while waiting for them to 'discard cards,' and then it just became their turn and I was left kind of frozen in that 'waiting' animation.
