To reproduce:

1. Open the project, attached by the tester (see link in the edit)
2. Open the "Tanks Timeline" scene
3. Enable the Main Camera
4. Select the Timeline object in the Hierarchy and scrub through the timeline to see the movement (everything works as expected)
5. Enter Play mode (animations work as expected)
6. Stop the Play mode
7. Expand the Player Motion object in the Hierarchy
8. In the Player object, assign Humanoid animator controller reference to the Animator component
9. Scrub through the timeline (everything works fine)
10. Enter Play mode (animations are wrong)

Expected: Animator doesn't have any effect on the way the animations are played in the timeline OR have a button or toggle in the inspector to override the Animator and other conflicts completely
