I sold Lichtenfels to HREmp Bohemia as the Netherlands after accidentally taking it in a war and they gave me 100k ducats in return. I am shocked Bohemia can afford this and that they'd be willing to pay that for such an insignificant piece of the HRE. This effectively set me up to run a significant deficit for the entire rest of the game and seems to need to be toned back.

Maybe it could instead scale with factors like development?
