It's a bit frustrating that we need to process the raw ores 1 by 1, even at higher levels.
I think it would be nice if the higher-level crushers could process the Raw Block.

Adding that recipe I think would be easy, and an incentive to upgrade to the other levels of crushers (besides the ore duplication.)

Additionally add a block of raw Iésnio

I had no idea raw blocks existed haha
That sounds like a good idea - btw you can already add this on your own via datapack, but I can look into adding it by default
