I wasted all my traitstones to level up this Kingdom to Power level 5, so I could get the bonus on it´s Skill. Saddly, right after that, I noticed It is still +1 to hit points on the Kingdom Level tab.
I hope you can fix this asap =(
Also, Just leveled my Whitehelm to level 9, but the Tribute chance is stuck at 20%. It should be 30% at levle 9.
