If you have been removing mods to slim down your setup, you might end up with Moonlight Core Mod sitting in your folder with nothing left using it. Because it only runs background tasks for mods that require its shared code, keeping it around by itself changes nothing in regular gameplay. You can quickly test whether any remaining mod still depends on it.
Testing Your Mod Folder Safely
Do not delete files outright while trimming your list. Instead, run a quick launch check:
1. Close Minecraft completely so no game files are locked.
2. Open your Minecraft game directory and navigate into the mods folder.
3. Move the Moonlight Core Mod file out to your desktop or a temporary backup folder.
4. Launch the game normally and watch how the startup process behaves.
Reading the Startup Result
- If the game reaches the title screen: None of your remaining mods require this base layer. You can leave Moonlight Core Mod out of your mods folder and continue playing.
- If startup stops on a warning screen: Your mod loader will pause before the main menu and list the exact mods asking for Moonlight Core Mod. Close the window, move the library file back into your mods folder, and relaunch the game.
