active rag dolls and NavMeshAgent's

so I have an active rag doll system I took from GitHub which was made by a youtuber but im having no luck in figuring out a solution, origanly I was going to have an empty object that used its own NavMeshAgent agent and the active rag doll would try and follow it but I quickly ran into a problem if the NavMeshAgent goes behind it will lose track of it and also it looks awful so im wondering how can I apply a NavMeshAgent agent to the active rag doll itself because in its current state I just makes a beeline for its target

 

Blend physics and navigation is not a good idea.
The youtuber Dani had thet problem and made:
-Enable the navmesh.
-Get the next point to move.
-Disable navmesh.
-Move the character (I guess rigidbody.MovePosition)

 

thx
