Mods:

• Vanilla Hammers
• Ore Excavation

Problem:
Ore Excavation apparently thinks that your tools are shovels of sorts, because I can excavate sand, grass, dirt without problems. When it comes to stone on the other hand, it only does the 3x3.
I'd like to use obsidian hammers to make long 3x3 tunnels, without having to remove every layer by hand. I already tried different means of adding your tools to ore-excavation using their tool overrides, Tool whitelist and alternate tool checks. None of those worked.

I did stupid, it is not your mod i was using, since yours if for fabric. Sorry!
