Thanks for your reply,
Yes all the layers are 3d and there are no accidental key frames added.
To give you a better picture the map is zooming from one part of the map to another and a camera is applied to give the map a slight tilt. Surely by parenting the path and location markers to the map they should move with it, but when you play back the animation you can see them sliding away from where I put them.
