Custom Character Attachments for Resizing?

I’m not Exactly sure where to post this but I was wondering what the issue is? I have created RigAttachments and used the :BuildRigFromAttachments() Function. Animating the model works perfectly but when I try resize the model using the Humanoid Size values it seems to glitch and mess up? Each rig attachment is in the same Global position so for example the Neck Attachment inside head and the one inside UpperTorso are both in the same position. I’ve done this same thing for the other Attachments etc

Left is what it looks like after Resizing whilst the right side is the way it looks without that.

Animating works completely fine though?

Any Ideas what I am doing wrong?

Try changing the values in the children of Humanoid.
