not enough spine bones for PM

[swift tapir]

so this is original skeleton

and here with added bones

this is how it looks like in gmod

if im trying to remove the new spine line from the model's QC file it goes like this

[swift tapir]

importing compiled result back from gmod to blender - the problem bones is first spine bone which gone much lower than it should be and both clavicles with neck, theyre moved higher than it should be, so it shouldve look like on this screenshot:

(also hands-weapons positioning is weird, and fingers for left hand broken)
