Plagues question

[GodMan]

They have to be programmed to cull the player population isn't it?
It can't be that every time I'm getting into higher pop count suddenly a plague comes trhough my country and culls a third of the pop.

Even when I just became an HRE the plague literally hit few months later and killed 5 mil pops, ending within my borders and barely damaging my neighbours

No, the game does not target specific countries. Plagues come and go randomly, you just feel like everything is about you.
