More Balkan States + Reworked Karelia Ultimatum
This is a vanilla hoi4 version of my millennium dawn submod "MD: Better Yugoslav States" (will probably get renamed to better balkan states)
This mod also fixes the Winter War ultimatum and now the Soviet Union can negotiate with Finland for a minor border adjustment if the opinion is high enough (the war can still happen if they refuse to give either the entirety of Karelia or South Karelia/North Leningrad)
