Krakatoa 0xB3E32901

Anyone get this error? I get it sometimes when rendering and sometimes just when working on a graph. It crashes to desktop, no opportunity to save the file.

Window Title: Krakatoa Error
Dialogue text: 0xB3E32901 error: Corrupt Operator

I’ll try to uninstall, delete everything Krakatoa and re-install it and see if that fixes it. It happens when using Stoke 2.0 so that’s why I am posting it here, not sure if it happens with Krakatoa alone.
