Is Nation Collapse bugged in EU3 Complete. I just had it happen to Russia and I came out looking a lot better - thought all was lost. Nothing seemed to have changed for the worse afterwords.
What actually occurs at a nations "collapse" depends on the types of rebels you have. Pretenders will give you a new monarch/slider moves to decentralised and aristocracy, peasants will give slider moves to decent + free subjects, patriots will take provinces to nations of their culture group etc.
2 quick questions related to things I find annoying in game.
1) When I am HRE, I randomly seem to acquire new territories like Krain or Osel with absolutely zero notification. I understand the imperial notes system when an AI nation is HRE, but I dont even get any notificaiton when I randomly receive a far flung province which then proceeds to revolt the very next turn. Half the time I can't even gift them back to their rightful owner as they have lost their cores.
2) How come an enemy nation can just walk into my colonies with 1000 units and take control, not occupy, just take control, where I only occupy if I walk into his? Then if I get my territory back in peace negotiations, it has his culture and hence less productivity and higher revolt risk... makes no sense.
1) get the latest patch - they fixed this. it is a result of nations owning land in the HRE they don't have a core on and then giving it up via the "a formal request" event.
2) when you have an army stationed in a colony select the army. on the tab at the bottom you should have two options - burn colony and seize colony.
the change in culture would be due to them sending a colonist to it whilst in their possession.
