The King refused to show his HPs in the Stats Banner. It was probably due to him having Hp in the double digits and everyone else having Hp below 10. He felt superior. Now he is more ground to earth, as the textbox was enlarged to acommodate double digits number.

If you don't feel like downloading the new fixed version, just now that the King has 10 hp (12 if he speaks German), and that when you bring its HP below 10 it will be reflected in his Stat Banner, as every other piece. Also above his head, the health bar just won't lie.
