Seems to be an issue with FTBJanitor.

Any way to fix it? Do you know off?

You should report the issue to them so they can look into it. In the short term you should be able to just remove the mod, I think it's only there to help debug issues when making the pack.

It's a base mod needed for other mods so that a no go on removal. I've messaged them just need to wait on a reply.
