Trace a MythicMobs skill reference across several files

Applies to: MythicMobs; match the linked maintainer documentation to your installed platform and release.
Documentation checked 9 November 2026.

A skill may fail after moving configuration files even when the visible action looks unchanged. Follow its internal references and load errors before recreating the entire content pack.

Check the installed content

MythicMobs separates mob definitions, skills, targeters and triggers. Keep the internal IDs stable while testing a behaviour change; changing a display name does not require replacing the mob ID. Use documentation for your installed MythicMobs release.

Work through the change

1. Record the failing mob ID and the first skill name called by its definition. Search the downloaded configuration copy for that exact ID, including spelling and case.
2. Make a simple reference map showing each called skill and the file that defines it. Note IDs defined twice and names that appear only as references.
3. Read the startup or supported plugin-load errors from the first failure onwards. Correct one unresolved or duplicate definition on a staging copy, then repeat the same load.
4. Trigger the shortest skill path that demonstrates the fix. Add nested branches back in sequence so a later failure does not hide the original reference problem.

Verify the result

Every referenced skill in the tested path should resolve to one intended definition. The server should load that path without a missing-skill error and execute the expected action once.

If the result differs

If a reference still fails, check whether the enclosing YAML structure prevented the definition from loading. A correctly spelled ID inside an invalid file remains unavailable to other skills.

Keep a recovery path

Restore the previous file layout from the content backup if moving files introduced the problem. Keep internal IDs stable during organisation work, and do not reset player or world data to fix a configuration reference.
