[Pocus]

I see. Very randomised so, thats must explain why many mountains were pretty low on resources.

I have noticed a thing too, the sites which give resources dont give their full amount, even at 0 unrest (dont know if it is taken into account). How can it be?

just checked again a pbem game : I have a mine of superior iron (+25 res), 0 unrest, but still my province only produce 15. Is it because without castle the resources from sites are halved too?
