Hello. Using your mod, I noticed that the items do not have russian translations, although the interface translations are present. I reviewed the translation file to determine what is included and what is missing.
So, in this file, I added the missing translations for advancements, item names and also slightly changed the descriptions for items to make them clearer for Russian speakers.
I would be happy if you accept my corrections and add them to the mod.
Thank you.
P.S. At first, I wanted to send it via a pull request, but it didn't work out. I couldn't figure out how to do it.
