Hi, I think that this could be changed...
Sandomiersk was Polish Duchy not Russian, so should be using Polish form - Sandomierskie (like PROV531) not Sandomiersk.
Krakow could be changed to latin form Cracovia, like Mazovia (Mazowieckie)
In 1066 Scenario, Pommerania and Mecklemburg provinces are Werstern Slavic, but rulers are still Lithuanians...
