yes as an assistant when I go to her and press X the clothes are different from what I've selected or when I want to change them it won't change
the red dress won't come off
and her Hinata outfit is showing Aoi yellow outfit when you press E and she's wearing it it shows an empty dialog box with Aoi name on it
