Mods Not Loading or Harmony Errors
Tags: mods, harmony, troubleshooting, server
Most mod load failures come from folder structure, missing Harmony, or EAC conflicts. Use this checklist to stabilize modded servers.
Verify the Mods folder
- Use a single
Mods folder at the server root.
- Avoid nested folders like
Mods/ModName/ModName.
- Remove duplicate versions of the same mod.
Install Harmony correctly
- Install the official TFP Harmony mod once.
- Keep the same Harmony version on server and clients.
- Update Harmony after major game patches.
EAC and crossplay
- Most mods require
EACEnabled set to false.
- Crossplay servers must stay vanilla with EAC on.
- Do not mix modded clients with vanilla servers.
Isolate conflicts
- Disable all mods and verify the server loads.
- Add mods back in small batches.
- Check logs for the first red error after each batch.
