Troubleshooting Missing Dependency Prompts

Diagnosing Startup Warnings

If you launch Minecraft and receive an error screen indicating that a required library is missing, Data Anchor may be the cause. Many mods rely on Data Anchor to attach data to players, levels, and block entities. When one of these mods is present without Data Anchor, your mod loader will halt the loading process to protect your game from starting in a broken state.

Resolving the Issue

To fix this error and load into your world:

1. Check the startup message on your screen to identify which loader (Forge, Fabric, or NeoForge) you are currently running.

2. Verify that Data Anchor is present inside your game directory's mods folder.

3. Confirm that the file in your mods folder matches your current loader platform. While Data Anchor supports Forge, Fabric, and NeoForge, running a build intended for a different loader will result in the game failing to launch.

Once the appropriate file is placed in your mods folder, restart Minecraft. The dependent mods will recognize the library and the game will boot directly to the main menu.
