in my mod you can strip a wood block and a "Bark" will spawn from it. some how your mod does not let it spawn the item. can you check where the error is in your mod with my mod.

Sure, I can take a look, where can I find your source code?

I downloaded https://www.curseforge.com/minecraft/mc-mods/the-common-sense-mod and opened up the jar, found some recipes like data/common_sense_forge/recipes/acacia_to_bark.json. Is this where the stripping behavior is defined?

{
  "type": "minecraft:crafting_shaped",
  "category": "misc",
  "pattern": [
    "01"
  ],
  "key": {
    "0": {
      "tag": "the_knifes"
    },
    "1": {
      "item": "minecraft:acacia_log"
    }
  },
  "result": {
    "item": "common_sense_forge:acacia_bark",
    "count": 2
  }
}

I also see a BirchUseProcedure (and other woods). Any info you can give me about how these things work would help.

it is the GettingTreeBarksProcedure
