Hey Byron,

I wonder if you're running into gimbal lock. I seem to remember having a similar issue and reorienting with nulls.

I just tried this expression in place of the Auto-Orient and it is still flipping. 

lookAt(position, position.valueAtTime(time - thisComp.frameDuration))

I'm getting twisting on my Auto-Orient 3D layers. But I don't have an expression on the position of the object. It's mostly happening when the layer goes vertical. Anyone run into this?
