Without really thinking about it, I've employed Lydia as my steward in Lakeview; but now I don't have a housecarl in Breezehome anymore. I'd like to fire her and replace her with some other follower and let her head back home.
(I know that I don't need a housecarl in every house but it's bugging me that my one house is now "unguarded".)
I can't find any way to have a steward step down or be replaced; there's no dialog option to ask her to resign and I can't seem to ask any other follower to do the job. Am I missing something?
