The compress items keybind lets you create a full dust out of just one tiny dust. This is on the latest version of the pack.

Hm they said they fixed this wtf

Cannot reproduce, could you provide some more info?

Oh yeah sorry. I just mashed k on a stack of tiny brick dust with the crafting table open and it turned the last into a full dust with only 1 left in the stack. I tried it again with splitting the stack into several stacks of one and it turned each into a full dust.

Yep this is confirmed. It looks like there was an issue about this on the CraftingTweaks github but they closed it without any changes so I'm not sure what's going on there as of now.

I really don't want to have to remove this mod again, but this is pretty game breaking.
