My .blend only renders a black screen after 57 frames.

I have a weird bug where images only render if the current frame is less than 57.

zanimbroken.blend (799 KB) This is a .blend without the stuff I was making, the bug still happens. Also I was using the cg cookie rig, I think that may be causing some nonsense.

Look in the Video Sequence Editor window. You have a scene clip that ends at frame 56.
Either extend it, remove it or in the Render / Post Processing panel turn off the Sequence option
