Why do my commanders keep dying of disease?

Naa, it's more fun when you build a castle over it not knowing what is in store.

One time I built a castle on a high-resource province but it had a magic site to cause unrest. Since I really needed that province's resources, I set the tax to 0. For some reason, 5 unrest remains there forever. I even patrolled it with 60 units, that 5 unrest will never go away. Oh well, probably because it was a magic site that caused 5 unrest a turn.
