Uncommented and updated LightStorageMixin to LayerLightSectionStorageMixin to catch the null pointer from #403.
This seemed to have fixed the issue as I could generate 631551 chunks with chunky pregenerator on the nether without any crash.
This fix already existed on your code on 276c642 but was commented on 90e84f4 when updating from fabric 1.16.1 to 1.16.2.
