OK nevermind that's caused by the texture combine of two different Burnice models

Playermodels are having purple texture error

@That cat from Oured The neck is likely not having enough weight assigned to it and cause the head to start flinging around wildly.

Add $jointmassbias "valvebiped.bip01_neck1" 5 to the QC file under the $jointconstrain lines for valvebiped.bip01_neck1.

@Astarod
turns out, that was caused by the neck collision mesh (which i often add in my later works with clavicles too), while it helps in posing the head better with tools like Ragdoll Mover, in turn it sacrifices posing stuff using the phys gun which may make the head mesh less stiff and more prone to jittering about.

either i have to remove the neck phys mesh which fixes the problem, but in turn omits better head posing, or don't which said problem will still persist while keeping better posing with that aforementioned tool.

Bro, there's a bug with the ragdoll: if you try to grab her from the head with the physics gun, her head starts to twist uncontrollably. It happens with both ragdolls.

The man, the myth, the legend
