because renpy keeps copies of your saves in your hidden appdata folder. go into any folder, click on "view" and check the option to show hidden folders; now, your saves are gonna be in your "user" folder (whatever you called your pc): user -> AppData -> Roaming -> RenPy -> Tvern_of_Spear-1, delete everything, sync folder included (or just move them somewhere else, just your persistent save for the gallery, whatever, your call)
