For some reason you are using a very old version of the BYG mod?

@warjort 

I tried using the most recent version and the same error came out, so I changed it to another one but it's still the same.

Can't help you if you don't show the debug.log with the updated/latest version. We have no psychic powers.

But, if there really is still a problem with BYG's latest version, you should contact the mod author.
