Hey!
I was playing on 1.20.1 and noticed that those items can't be crafted
Idk if its a bug because I have many mods installed, or if they will get their recipes in the future
P.S. I really like the mod!

Just noticed some bookshelfs also don't have any recipe hehe xd
And vertical slabs
Help

Just to confirm, you have quark installed?

Yes

Alright, will look into it!

Hey, it's me again!
I've found what the problem was
I had chests, bookshelves and other blocks disabled in the quark config, didn't know it will also disable yours

Alright! Which bookshelves and vertical slabs were missing recipes, by the way, if you remember?

Sorry, I haven't seen this :c
The blocks are chests, ladders, vertical slabs, vetical planks and bookshelves
