Re-positioned all the front legs - works fine

Moved the back legs .... rider now flicks bacwards and forewards.


None of the things I thought were responsible can be ...since the test showed they didn't cause an issue. The rear legs were not moved significantly more than the front
Unless I am misreading you, you should never move the bones (except the root bone) in an animation! Otherwise you will enter a world of pain... because the way quaternion animation works, the position of a bone changes the effect of the rotation. And since RTW animations do not store the position of the bone (except the root bone and the pelvis bone) in the animation files you will get unpredictable and undesirable effects.
