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.

This mod adds a warning screen when attempting to load a world with missing mods, tells what mods are missing and provides an option to go back to the main menu or proceed loading.

Forge used to provide a similar feature on pre-1.13 versions, but has since been removed.

An icon and tooltip is also added to the affected worlds in the selection screen

Useful for debugging mods without accidentally ruining a world. Clientside only
