: Various combat and movement modules that the main Meteor team considers redundant or too "blatant". Final Verdict

Meteor’s legacy package system (Atmosphere) uses numeric identifiers. While rare, some internal errors reference package build steps. “Addon 1211” could theoretically point to a specific build hook or plugin that failed to execute.

To understand why an addon is rejected, one must first understand the loading chain. Meteor Client and its addons are built on the Fabric mod loader.

Remember: the key is to read the verbose build output, not just the error message. The number 1211 is a clue pointing toward a specific build thread or process. Follow the steps above, and you will turn a cryptic rejection into a successful Meteor addon compilation.
