Hi! i tried to start a playthrough in eu4 but with an alt history map, so i left ck3 running while i was observing, with a mongol empire that reached all the way to france and then fell, leaving a shattered europe (i attach an image of the end game in ck3 and start in eu4) i was planning on playing with sardinia and corsica, as the ai took advantage of the small duchies and expanded through northern africa and a good chunk of western europe, but when i converted sardinia had 3 PU and owned a small amount of land in comparison with how it ended in ck3. I tried a few things to see if i could get the entire kingdom but nothing worked as it still was divided in those PU (tried changing the modifier of vassal split off in configurables but didnt work) i was wondering if there is a way to stop all the countries in europe from getting divided in PUs (not only the ones in Sardinia and corsica but the others like Castilla, Anatolikon or Norway) sorry for bad english in advance.
