Sadly, we can't provide support for this kind of modifications. You may be missing a startup argument or something like that.

Could you show something like a screenshot? What exactly do you see?
If you are trying to boot up cracked MC, that's not supported.

If you get the westeroscraft, you have to create your own distribution.json with Nebula
