Create a scene where generic and humanoid animations are applied to the same humanoid character (or use attached scene)

Try to scrub the generic animation (MoveBone on Marine_troop in example)

--> Inspector has lots of repeated messages saying "Binding warning: Some transforms are animated by both a Humanoid animation clip and a Generic animation clip. Only the Humanoid clip will be applied on those transforms..." (Warning is ok, but too many repeats)

--> Console error shows multiple errors with
"String too long for TextMeshGenerator. Cutting off characters."
