My game was loading, then it suddenly crashed.

Thanks in advance for any help.

In the config it said baubles, so I installed the baubles mod and it worked.... Weird...

Caused by: java.lang.NoClassDefFoundError: baubles/api/cap/BaublesCapabilities means that a mod (likely whatever nvg is) tried to load a class from baubles but failed. As such you should probably report this to the nvg mod, since it should either declare that it depends on baubles explicitly, or not try to load from baubles if it's not installed.
