Shadows Freak Out in Animation!

[jjanke81]

The shadows flicker, move and make incorrect geometries in my exported animation. Why does this happen? How can I correct it? Thanks!

Well, that's the dreaded flickering bug probably:

As it says, try to avoid crossing shadows/lights borders with your camera path. You can make this less annoying if you turn off shadows and only leave "use sun for shading" on in the shadows dialog. This will not cast shadows on your (bare) ground plane however so if you need them, put there a horizontal face to receive these shadows.
