Not sure if I written this before, anways, When I do an animation, and then Click in "Render NURBS" my animations changes. I'm not sure what animations this bug effects but In this chase, it's the DOLLY. So anyways when I check in Render NURBS (for everything) and When I replay the animations, it looks different. In this case my dolly "zoomes" in in a different location. If i Deselect the "Render NURBS" and save, and restart the program. It works as it should again.
Not sure what triggers it though.
