Hi 
Yes, its working fine for me.
To get a proper working ragdoll it is best to set it up from scratch.
At the end of the post i’l add a video by a channel “John Connor”
who made a good overview of how to create one.
In my project i have a ragdoll already setup, then i add a physics body to the root
of the skeleton. resize it so it is very small between the feet & set its physics from default to kinematic & set collision response to disabled. Add a constraint to it targeting the pelvis. The constraint itself has angular and linear limits all set to free.
Now i have no idea why this would fix any of the above said issues but since i do have this and am not having any issues its worth a try.
Also if you are working on ragdoll’s i would also add a gdc talk about physics from uncharted 4, its worth a look some good tips in there.
Let me know if it helped.
