I was playing as Bismarck and I noticed that there doesn't seem to be a +2 health bonus to the cities. I haven't tried other leaders with the Expansive trait but I was wondering if this is a bug because leaders with Charisma get the bonus to happiness in their cities.

If you have looked into this issue would you please explain it with numbers. i.e. how many free health points a non-expansive leader starts with and whether the expansive leader starts with the same number or not. Difficulty level may affect the number (I am sure it does for happiness but not sure ATM about health). Also notice that you start the game with civics that apply negative health. Did you take this into consideration?

My mistake, it appears as +2 from Civilization.
