Changing character's rotation during ragdoll

This is related to another question of mine: https://answers.unrealengine.com/questions/295379/uscenecomponentsetrelativerotation-has-no-effect-d.html

During ragdoll, I wish to change my character’s rotation but let it keep falling according to gravity. I cannot stop simulation at this point because falling would be interrupted. For UE4.8, I was able to do this by calling USceneComponent::SetRelativeRotation. However, the call does not work in UE4.9 anymore. Can anyone tell me how I can achieve this in UE4.9? Any pointer to UE4.9 documentation about the changes which stops USceneComponent::SetRelativeRotation from working in this situation? Thanks a lot.

I am still having the same problem with UE4.10. Is what I am trying to do not making any sense? No one here is doing something similar? I am afraid I will have to stick with UE4.8 forever. Someone please help!
