Is this on 1.0.0 or 1.0.1?

Uh, fast! It is the latest version 1.0.1 on 1.19.2.
I am using Custom Stars too, not sure if this is related to this bug: https://www.curseforge.com/minecraft/mc-mods/custom-stars

Custom stars may be the problem, although I can't be sure. Try running the mod without Custom stars and let me know the result.

Yep, removing Custom Stars resolved the problem for me.

Alright. Celestial has its own star customization system, so there might have been some conflict there.

So there is no compatibility workaround possible?

Probably not. Whatever you are trying to do can probably be accomplished with Celestial, so you could try that.

Alright, thanks.
