I have a character who has 5 kori and wants to be daimyo. Unfortunately, though I do have a free daimyo slot, I can't seem to appoint him, because (if I understand the rules correctly) he needs to own at least one kori in the daimyo's kuni. But since he already owns 5 kori, I can't do this without revoking one of his existing titles, which would seem to negate the benefit (and then some).
Is there anything I can do about this? The only thing I can think of (aside from "deal with it") is not to hand out so many kori to each character, so I can hand out a kori when it's needed to appoint a daimyo. Is there a better solution?
