Here is a small snip-pit from my MultiMC Log:

I have also posted this report over on the biome bundle Github just in case ~

I'm not using sponge and i got a reply over on the biome bundle page

I was told they wont be taking bug reports until the 1.11.2 build of OTG has been officially released

and sorry for the faux bug report ~

Hey, are you using Sponge by any chance?

Thanks for the bug report, looks like this is happening with the latest version of forge (13.20.0.2315), the recommended version (13.20.0.2228) should work fine though. Will fix this a.s.a.p.

Could you grab the latest dev version from the comment in this post and tell me if that fixes the problem?

Thanks!

I have done what you asked it is going well so far ~ thank you ~

Glad to hear it, you're welcome :)
