England has five colonial nations. England itself has 75 warscore cost. If I demand CNs in the peace deal it would take more than 100 WS. If I demand non colonial English provinces only I can full annex England and inherit their CNs in one peace deal. The problem is unfinished colonies count as part of England's, and since islands that are not part of colonial regions also show as giving 0 OE, I have to either have all maps, which I don't, and look around the world to find every island and unfinished colony that belongs to England, or click through every province in the peace deal until I find some magical combination of mainland + 0 OE provinces that lets me full annex them. Unless I'm missing something there's no other way. I can't see all of California so I don't know which provinces are not fully colonized.
