I tried out the Datapack and it seems like it works fine? I have to check if it overwrites tectonic tho

Very odd, I might just recommend trying to redownloading the Terralith mod? Not sure what else would cause it.

I have to note that the same crash applies to Amplified Nether and Nullscape too. The modpack I'm using is quite big and may cause trouble because of its size
