I can't stop my spellcaster using broom?

Thanks @MaggieMarley but I don't use mods :( I tried rolling back the save, but I think it is when the game takes the spellcasters to the Realm (the sim I'm playing) sees him there (the one with the broom) and the game obviously has given him the broom in the situatonal event u know, as he is not wearing the clothes I assigned him, so the game has dragged him there.
