TimelessLib is a dependency for other mods. If one of them needs it and can't find it, the game often won't load at all.
Signs TimelessLib is the problem
- The game stops during launch with a message naming TimelessLib as a missing or required mod.
- A dedicated server shuts down on startup, and its console or log mentions TimelessLib.
- You recently added a new mod, and the error appeared right after.
Steps to fix it
1. Read the error message carefully. It usually names both the missing library and the mod that needs it.
2. Add TimelessLib to the same mods folder as that mod.
3. Make sure you only have one copy of TimelessLib. Delete any duplicates.
4. Make sure the copy you add is built for the same mod loader as your other mods.
5. On a server, repeat these steps in the server's mods folder, not just your own.
6. Relaunch and confirm you reach the title screen or the server finishes starting.
If it still fails
- Open the latest log in your game's logs folder and search for "TimelessLib". The surrounding lines usually point to the actual conflict.
- Remove recently added mods one at a time to find which one is causing trouble.
- Check the requiring mod's page for any extra libraries it needs alongside TimelessLib.
