saving camera paths of animations

[sir.orange]

Hi there,

I was a little surprised that the animation in the time-line disappeared when having rendered it completely. I had an interior scene with 4 camaras creating the path and a second path for opening a door in the scene. The time line of the door-opening ist still there, but the main path is missing.
How can I save those camara paths?

Very strange. Any chance you can share the scene so we can take a look?
