Skydiving Issue - child rotation causes parent to rotate?

Having a strange issue that hopefully one of you smart folks might be able to shed some light on. I'm working on a skydiving to parachuting mechanic. I have a helper object as a parent to my camera, allowing g for free orbit about the player without affecting the player transform. Now getting an issue that rotating the Camera Pivot which is a child of the ThirdPersonController (TPC) causes subtle but noticeable rotations on the TPC. After a short jump and only moving the camera my TPC ends up severely rotated. Anyone ever ran into, and hopefully solved a child rotating causing rotation on the parent? Thanks very much for your time!
