In my recent game, Remake worked most of the time, but one time instead of allowing me to Remake a Catacombs (value 5) into a card with exactly 1 more (Gold) it insisted I remake it into a card costing up to four. My opponent granted an undo so I could see if it was a one-time glitch, and it still happened. It even happened after I refreshed my browser. Screenshot attached. Eventually I continued the game without playing Remake that turn. It was game "#163252773".
