Tried changing governments, nope. I thought westernizing would do it, notta. Then tried becoming the Chinese nation after Manchu was annexed by somebody else, and that just resulted in a game crash.
I'm assuming Manchu imperial administration was in there to allow you to get rid of factions since if you load from a scenario Manchu China has no factions, but doing that in-game doesn't seem to get rid of factions, and when I try to reload that save gameit crashes (already posted in bug reports).
Is this the right way to get rid of factions, or is there another way I'm not noticing?
