Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Requirement:

Error: listen tcp 127.0.0.1:11434: bind: address already in use then skip it and then run:

Radical Honesty Protocol

Grox-Style Hierarchy
Designed for the Overlord playstyle, this mod allows for total control over your worker force. They are optimized for absolute obedience and peak efficiency in resource gathering and base expansion.
