Troubleshooting Missing Deimos Lib Warnings on Startup

When playing with mods that require Deimos Lib, Minecraft may refuse to start or display an alert if the library is not detected in your mods directory.

Understanding the Dependency Error

Deimos Lib functions as a core library responsible for handling data generation, recipe registration, and configuration screens for dependent mods. If a mod in your pack relies on it, your mod loader will halt the launch process during startup if Deimos Lib is missing. The launch screen will typically display an error message stating that a required library is missing.

Verifying Your Mod Directory

To fix this issue and allow your game to launch, follow these steps:

1. Close Minecraft and open your local game directory.

2. Open the mods folder where your active mod files are stored.

3. Verify that the Deimos Lib file is present directly inside the mods folder and not inside a subfolder or zip archive.

4. Ensure the file corresponds to the correct mod loader you are running, as Deimos Lib works across multiple loaders and Minecraft versions.

Once placed properly, start Minecraft again. The game will proceed past the startup phase and load all dependent recipes and features.
