I just uploaded 0.1.13 that I think will address this.

Are you using other mods beside the Subterranio's?

yes, a bunch, still getting an error

I did a bit more cleanup in there, can you try version 0.1.14? Hopefully it's fully fixed.

Can you provide your %APPDATA%\Factorio\mods\mod-list.json info if it is still not working? That will help a ton with fixing it
