When you leave ShowCardState, any click you make is registered in the state you enter, which is InGameState. This causes clicks on areas where cards are, a majority of the board, to be registered as clicks on them. This is problematic since this is not the intention when you are in ShowCardState, and will result in unwanted behaviour down the road. Not high priority, but must be fixed before game is shipped.
