Well now I have run in to some really bizzar camera issue both poped up in the same scene.

First a simple straight position change from a to b, I hit animate and the camera desides to go through neverland to get to b from a. 3 different cameras same out come. It's just like a 3 meter straight slide but the camera goes way out of the scene in some strange orbital spinning path 

So I decided to do the camera on a plank; drop in a cube flaten it stretch it to the right camera distenc, drop it on genesis hip, move it so one end is on genesis, drop the camera on the plank and move it to the other end. Animating the camera will follow/track the figure nicly; though uinsteady. Got it set up, clicked animate and... the camera vanishes. More over the scene seen through the vanished camera is just genesis rigging, nothing else is in the scene; renders fine. It's easy enough to make the camera visable because the bug just unselects visibility. Select visibility and the camera has trippled in size I can't find anyway to get the scene back when viewed through the camera. 3 cameras, same thing all 3 times.
