Hi, i have this error -->
Weird, I never had this bug... I tried to replicate it but found nothing... Looks like it's early in the game. From the image it looks like you used 2♠ to buff your character and then clicked the play button. Do you have any other detail? I'll try to look more into it.
I think I stopped selecting a card and hit play. I don't remember well...
I can't replicate it again :(
Good. hahaha ;D
Anyways thanks for telling, I'll try to find it still!
