I tried to play a sweetened snowflurry in my Arena game on iOS, but the card became stuck in a half played state in my hand leaving a mini copy and the original in my hand but neither were interactable. I ended up playing other cards from my hand to see if there was some sort of disconnect error but they all played fine. Obviously not ideal to be unable to fish for answers on a key turn.
