Here is the error when loaded with the Arcanyx planet mod.

Failed to load mods: rigor-module/data-utils.lua:245: attempt to perform arithmetic on a boolean value
stack traceback:

Thanks for reporting! I'm pretty sure I know the cause, and will get this fixed. Did you just download (or update) either Rigor Module or Arcanyx?

In the meantime, you can enable "compatibility mode" in rigor module's startup mod settings which will probably get it to stop crashing.

So I just downloaded the latest of Arcanyx and updated rigor yesterday to the latest version.

This should be fixed with v1.1.15.

Can confirm the new update fixed the bug :D
