Using the Parent to Vertex node parented to a Null cause the child objects of the Parent to Vertex node to rotate at double speed of the parent object when rotating the Null.
Connecting the Continous Modifier with a speed of 10 to the Rotate Lights Null.
Lights should rotate at the same rate as the other objects.
Lights rotate twice as fast.
Lights can be replaced with objects resulting in the same behaviour.
Connecting the Continous Modifier with a speed of 5 syncs up the motion.
Math Modifier/Sine exhibits the same issue, albeit somewhat exaggerated. Maybe suggesting a scaling/amplitude issue?
Scaling the parent object doesn’t seem to make a difference.
