Emit is stuck in my household and nothing I've tried will remove him

please forgive me if this has been asked already. Before I finished the event quests, I added Emit to my household bc I got tired of making him come over every time I needed to progress to the next task. Now I can't remove him from my household. Can't kill him, can't split households as he doesn't show up in CAS or manage households. Even with mods, he's stuck. I even reloaded a save from 2 weeks ago(prior to me adding him to household) and he was still there. Any tips or ideas on how to fix this?
