Cutter node not rendering


I just finished creating/ animating a character, but when I render out the frames/video, anything with a cutter on it does not render at all. Any ideas on what could be causing this?

It also was displaying a mask I had made - it was ignoring the colour-override. I fixed it by disconnecting it from the comp, but it could be related.

Please help,

Is the matte inside a symbol? Try to create a matte without putting it in a symbol.

Is the color override relevant? By that I’m asking if it renders when the color override is removed.
