Stego tail plates counting as part of the body

Some of stegosaurus' plates on its tail count as part of the body and take the same amount of damage, fracture, bleed etc as the actual body

I was fighting a rex when it bone broke me with a bone snap to my tail, I tested it out with a friend later and I found out the tail plates were bugged

Stego should not be taking damage/status effects on its tail plates as if they were on the body
