Shoudn't we be able to craft 4 small pile of obsidian dust from one obsidian dust?

Currently the only way to get it:

Ahh, I forgot this was used in the marble recipe. All the small pile recipes were removed due to conflicts with MI ones when it came to compacting drawers. I'll add something to fix this.

That's what I was thinking

Maybe just grind the marble from the blockus mod
