This mod add a countdown to nauvis imploding, destroying Nauvis and altering the game loop. It also includes a new planet similar to a Nauvis Hellworld to acquire Nauvis resources later.
Throws an error when enabled with alien biomes. I didn't manage to copy the error but it has something to do with an autoplace of item big-rock. Might want to either set up compatibility with the mod or add it as an incompatible mod dependency.
