An assert fires related to the node index for the linked animgraph node being the same as the node index for the root node in the linked anim graph.
Can be worked around by commenting out the check, (AnimTrace.cpp Line: 653)
But the correct fix should be to correctly increment the node index.
Create an anim graph referencing a linked animgraph.
