Does this work if she's in the "Immobile" or beyond stages? Or they actually get deleted from the game since they can't really go out of their home.
afair/afaik when you delete an immobile character from the contact list, they get mobile again so they can appear in town again.
Havent't thought abot it until now - but that should actually be a way, almost exploit, to quickly slim a character down. Ofc with the downside that you have to be lucky to meet them again.
