RightHipRigAttachment not animating?

Hey.
I’m repurposing an accessory system to be used as a morph system, as there are accessory attachments for everywhere we need. However, we’ve run into one simple problem.

For some reason, there is only one attachment that doesn’t seem to rotate with it’s corresponding bone: RightHipRigAttachment

I don’t know why. LeftHipRigAttachment animates completely fine. This seems to happen on all places that I test.

Could anyone explain why this happens, and how I could fix it? I assumed I could just rotate the attachment based on the Motor6Ds, but I wouldn’t know how to go about rotating them to match properly.

Any help?
