Bug Ragdolls

Is there a way to get ragdoll ghosts to work?
when spawning a ragdoll ghost on the server, it just spazzes out and continuously builds up momentum until the appendages fly away

 

also, if any child has ragdoll joint / limited hinge joint component. clicking 'update component list' on ghost authoring throws this exception. which is because it assumes each linked entity group element is a gameobject child of the ghost, which it is isn't in this case
