Hi ! I just saw a guy having that issue on discord, with Voxelibre. I am not a player of nor mineclonia/Voxelibre, nor your mod, but opening you mod's code to check, I see that this error is because it doesn't find the node "default:steel_ingot".

The mod has default as optional dependency, but here, it doesn't check at all if the dependency is here, or if the node's registration is found, hence the crash.

You should either put default as mandatory dependency, and not optional, OR deal with the case of default not present.

Nor mineclonia, nor Voxelibre have default mod, because it is a Minetest Game thing.

Meaning that the mod is only usable on Minetest Game, and yet is tagged as usable everywhere, which causes the issue.
