There is minor bug with item shelf block's name:

This is not affecting vanilla gameplay, but to HYWLA user, it's a bit distracting

Oh I found it. aparently it uses its inventory name, the one that would appear inside a gui. Since I'm not using a gui and I had to implement those methods I simply added untralsated and sometimes random text in them since I never though they would be used. I guess with mods you never know

fixed

I have no idea where he's getting that name. its registry name is item_shelf and its translation name in english is Item Shelf.
I usually use the one probe but I've installed hywla just to see if it was working and it's showing its correct name just fine

Sorry, i'm not specific enough, i'm using Jade, fork of HYWLA and assumed it will work fine just like HYWLA, but i guess not :/
Yes, this is specific to Jade.
