Bad bug at Rendering an Animation?

[Anonymous]

I made an animation by a python script (see attachment)

But when rendering the whole animation from the beginning, one gets the that wrong result:

(There sould only be one text "Keine Tippfehler mehr")

But when I start rendering from an later frame, one gets the correct result (Starting at the first frame, where this animation starts):

Did I made any fault?

Or is this a bug?

Unfortunately one can not start a rendering by a script. Or is there a possibility?

Thanks in advance!

PS. I am using the renderer mental ray.

Does this happen in Maya as well or only when you render?

@saihtamIn Maya everything is correct. This only happen when performing an batch rendering.
