Insane-crafts-mod
This mod aims to add crafting recipies for uncraftable items. Currently it is only for Minetest Game, But soon enough it will be for other games too.
This mod allows you to duplicate ores in a sense you can get more things in less amount. Crafting recipies are for all ores present in the default mod. But they will be for other mods too. And not to forget gravel, dirt and all kinds of sands in the default mod are craftable.
Now MineClone 5 support has been added, for all overworld ores.
Great for when running out of certain materials
Its useful for getting materials you need without having to do a lot of mining. I did notice though when crafting gravel it gets rid of the bucket altogether instead of just replacing it with an empty bucket. Otherwise I haven't run into other issues.
