Minecraft ver.: 1.21.1
Mod ver: 1.6.0
Mod Loader: Neoforge

The actual drilling recipes dont show up in the latest release of the mod. Could configure myself using KubeJS, but I assume that like the 1.20.1 version it is in fact supposed to have at least some recipes built in.

Please post your minecraft log

Line 453 is the where the error specific to Excavation happened.

Before when I was testing it just wasn't working at all either but it'd seem since I updated Create to 6.0.2 instead of 6.0.0 the machine is at-least functional.

I released an update a few hours ago, that should fix it.
