Bug Hi I kinda have an unusual bug with ragdoll creation

Hi everyone, I've been banging my head for a couple of hours trying to figure out this one and I'm out of ideas, if you have any insights and can help me figure this out, I would highly appreciate any help:
When I use the ragdoll wizard all the rigidbodies are created without any issues.
except the head is like 100 times bigger, not even sure why.
the model scale is at 1.

 

The only time I had something on one end of a hierarchy get way bigger, was because the "parent" before it for some reason changed it's scale. So just shooting from the hip, I'll assume the head is attached to a neck, what does the neck scale look like from original prefab values? And is there anything that controls the "neck"?

 

Found the issue, the Armature scale was (100,100,100)

here is how I fixed it (4 year old video, is still relevant)
