Hm so population won't grow without + points in the growth scale? I gotta check this out, I guess I've played too much with Ermor, and never noticed this.
I thought that it is logical that the pop is growing without taking any points in the growth scale, also that it is growing faster when we take + points in the growth scale. This is rather odd!
*edit*
Just checked it. Pop just won't grow without +points in the growth scale.
