Issue with Animator to Ragdoll transition

[grave zodiac]

Hello, this is what my transition looks like right now.

That is to say, terrible

I have narrowed down this issue to joint angle limits, if they are set to (near) 180 for every joint, the issue is fixed

I assume this is because the animation is exceeding the angle limits, and thus enabling the ragdoll jerks it back very jarringly

However, I have no idea how I might fix this
