add great holy war crusader king can be chosen
del knight buff. It isn't effective as I expected... Instead, I increased the number of other very little.

add give spouse and child check is_alive

del vassal_levy_contribution_mult
add knight buff
add development_growth_factor

I heard The chosen AI are not strong enough due to supply limit, but system limited to fix it.
So I buffed knights and development factor instead of vassal levy contribution.
I hope the problem is solved now.
