Accesory always applies to head

idk why this happens and im clueless

As you can see, a back accessory applies to the head.
It welds to the head, although it IS a back accessory

I’m not too experienced with accessories, but what attachment is the Accessory using?

the video doesnt load for me, so I’m not sure if you’re doing things like using EquipAccessory or just parenting the accessories to the character
but make sure if the accessory has an attachment, that the attachment’s name is something like BackAttachment

also, if you’re setting those Accessory properties in a studio test, make sure to do that while you’re in Server mode (button to toggle between client and server is in the Test tab)

the back accessory, the one it should be.
