Question tail disconnecting from body issue how do i fix it

hi! I have a slight issue with my unity project- I try putting in a rigged physbone tail and attaching it to the spine but when I press play to see the movement on the bones work and move the character around the tail disconnects from the body fully I've tried everything to fix it even asking people that make avatars often! but nothing seems to work and if I upload it to vrchat and it is grabbed the same pulling away from the body issue happens I don't know what's causing it and I'd greatly appreciate help on this issue

 

You need to provide much more details in order to be helped here. How do you try to attach the tail? What's the setup? Does it use physics / Rigidbodies? Did you use a Joint?

 

oh! well its good now I figured out the issue the script wasn't attached to the bones and rather to the mesh
