I tested in the latest version 1.20.1, mod's version 1.20.1-07, with no other mods loaded except fabric and some premods.

There is the log.

Caused by: java.lang.RuntimeException: Category amethyst_imbuement:scepter_totem_augments specifies parent amethyst_imbuement:scepter_augments, but it could not be found

I would need someone to help update the localization. I can't update zh_cn myself.

I'm trying to update the lang file, then I will push it to you

I would need someone to help update the localization. I can't update zh_cn myself.

This is a solution on (mcmod.cn):

Translate:
Delete the en_us in assets\amethyst_imbuement\patchouli_books\glistering_tome, then rename the zh_cn to en_us

(should be data\amethyst_imbuent\...)

I think it's not the lang bug but the code bug.

Edit: OK I was wrong... It is the lang file bugs.

Update: This file contains new zh_cn translations, but NOT FULLY translated.
