Description of the problem

How to reproduce:

1. Go to Betweenlands (In overworld all works fine)
2. Press F5, or sit in rowboat

Actual result: minus my eyes

Pictures:

Astral sorcery has a config tweak to help with this, just add the betweenlands dimension to the weak render list, you dont see full constellation sky renders with it, but those are purely cosmetic and not essential to progression.
