Another bug: If you play a card which uses a slow animation with no player input (-1, 13, or 47), then click repeatedly on empty spaces, you can play free copies of that card for as long as the animation persists.
Thanks, should be fixed now. (Certain input is now frozen while playing a card. Hopefully no obscure interactions will softlock battles -- I'll do more testing later.)
If you cycle a card and then use an INPUT stone with the discard selector, it will think you have discarded and will only let you discard cards you can play (which includes 29, if you have any in your hand.)
