Version: (make sure you are on the latest version before reporting):

• Minecraft: 1.18.2
• Fabric: 0.14.8
• Powah: 3.02

Issue description:

Smelting/Blasting Recipe Output has to be a String:

{
  "type": "minecraft:blasting",
  "ingredient": {
	"item": "powah:uraninite_raw"
  },
  "result": "powah:uraninite",
  "experience": 0.7,
  "cookingtime": 100
}

Looks like a KubeJS problem.
