Biome light (vanilla) is still spreading, but the color components from your lights appear to be missing, indicating that the lightword's aren't being made properly. Did you accidentally remove compatibility?

Or was it something I did?

I'll play with it soon, but if one of you guys can take a look at it, that'd be great!

Nope... I'm just being dumb here. I didn't realize that there was a line in the config dedicated to this, and the user in question still had the config option set to it's default.

I may show up with a PR to balance colors later, but for now, please ignore.

Have a nice day!
