I was playing arena as a warlock. I generated the 8 mana spell super nova. I was able to play with the cards in my hand, but after I tried to interact to play super nova, ti was not working. I could not play any cards from hand. super nova was not able to play and I couldn’t play any other cards. my hand was not full. the only thing I was able to do was hero power and interact with the starship. I am on a Mac
