Skinned mesh importing bug completely breaks rigging currently

Help and Feedback Art Design Support
#1

currently whenever i import a skinned mesh model that uses backwards compatibility on seperate parts
(nameing meshparts the same as bones)

it seems to set part0 on all the motor6Ds to the rootpart which breaks the skinning.

EDIT: this actually affects all meshparts no matter how bones are parented and completely breaks mesh skinning even when not using backwards compatibility.

ive tried old and new models that used to work and this seems to be a reoccurring issue with anything that uses the backwards compatibility.

#2

this problem does not only go for parts using backwards compatibility.

all meshparts are affected and have part0 on their motor6Ds set to the rootpart.

this completely breaks any models imported currently

(to be clear i use blender and connect/parent my bones correctly, i then export this to a .FBX file and import it to roblox using the custom avatar importer.

this worked perfectly fine before but no longer works and for right now i cannot import any working skinned mesh characters/models.)
