I am playing as Sweden ~1537 AD and I made war against Russia with casus belli to get Nava province, located in Finland, I have claims on it. My allies are Poland and Lithuania, theirs are Bohemia and Hungary (coalition war). We pretty much defeated them in every battle, so the war score is greater than +10%. I'm trying to sue Russia for peace, as head of alliance, but when I try to ask for provinces the only one available is near Lithuania. Of course I can ask for that province to become part of Lithuania, not Sweden. Why isn't Neva on the list of provinces, or why is just only one province available to ask for ?
This way it's impossible to achieve my conquest war goals, so the war was pointless, I get no benefits, despite being active and winning all battles with my armies... Is this a bug somehow? Thanks for the response!
