If you report the factors, the elves will factor the composite after a while, and the colab script will continue normally. Of course, this is not the desired solution, as the time in between is lost with looping.

Please fix it and post it back at your convenience.
Thanks for the reply. I have a fix that I did somewhere else, but I haven't had a chance to dig it out and modify it for Colab. I think I had to do something odd like look for a color (representing composite) instead of the last term.

I hope to do this soon, but other things are distracting me.
