I dont know if this is a bug, but I think so
anyways while playing "Francia Orientalis" I have Serbia and Navarra as core provinces of my empire. I cant think of any historical proof for this. But maybe you only use it as possibilities for a permanent casus belli vs Francia Occidentalis and the East-Roman Empire. The same occurs when I play as Francia. Then I have a core province somewhere in the middle east, where I have no possibility to reach it by ship..
But this is by far the most fun I had while playing a computer game during the last months! I raise an empire as Francia and it becomes splitted (argh!) then I reclaim my "lost" as Francia Orientalis and while I am deep in French territory my empire gets splitted again
now with my empire splitted in 3 different parts with no connection between them I have to challenge Saxony and Lothringia in a war where they have 3 times as many troops as I have...
(maybe this stage of your mod is a little bit too tough)
So now while I am trying to make peace with Saxony the game crashed. But this occurs pretty often. Is it a problem of the mod or EUII in general?
