Find an ItemsAdder item that loads under the wrong namespace

Applies to: ItemsAdder; match the linked maintainer documentation to your installed platform and release.
Documentation checked .

An item can exist but appear under an unexpected identifier when its namespace declaration differs from the folder you expected. Inspect the loaded identity before renaming anything.

Check the installed content

ItemsAdder content uses namespaced identifiers for items and other assets. A definition, its generated resource pack and the copy downloaded by a player are different checkpoints. Keep content IDs stable and consult the documentation matching your ItemsAdder and Minecraft releases.

Work through the change

  1. Record the full item ID shown by the installed plugin, including the namespace before the colon. Compare it with recipe, loot and menu references that try to use the item.
  2. Open the relevant content YAML and inspect its namespace declaration. Check the complete sub-pack rather than assuming the folder name alone determines every supported layout.
  3. On a staging copy, correct references to the intended existing ID. If you actually need a new namespace, plan it as a content migration with preserved old definitions.
  4. Load the staging content and test one direct item retrieval, one recipe or reward reference and one existing player-held copy. Keep each result in the change record.

Verify the result

The same intended identifier should resolve through all tested references. Existing items should remain recognisable; a successful fresh give is not sufficient evidence that old inventory content survived.

If the result differs

If an ID remains missing, inspect the first YAML or asset-loading error for that pack. A file that never loaded can look like a namespace problem even when its declaration is correct.

Keep a recovery path

Restore previous references if the change makes existing content unreachable. Keep the old namespace available until a deliberate migration has a tested recovery path; do not remove it just to tidy tab completion.
