Enabling ragdoll problem

Working on implementing ragdoll.I doing it by disabling animator.It works,but when I disabling it at the first time it look like a mass of rigidbodies is too low.When I reanable animator it works fine until I change position of character, then again at the first time have this wierd effect. It looks like it's not calculated properly and somehow on second try it works fine, but changing position of character reset his memory of ragdoll colision... it LOOKS like this happens but as far as I know, Unity don't store this kind of data. Any idea why this is happening and how to make it work on the first try?

I don't use ragdoll provided by Unity... I used configurable joints to set ragdoll behaviors.
