About this Mod

WynnConfig Sync

Automatically renames a shared Wynntils config file to your own UUID on launch, no manual renaming needed.

What does it do?

Wynntils names its config files after your UUID. When you share your config with a friend, the file has your UUID in the name, meaning Wynntils won't recognize it on their end. Instead of asking them to find their own UUID and rename the file manually, they just install this mod and it handles everything automatically. This is especially useful in modpacks for creating config presets.

How to use

  1. Share your Wynntils config file with your friend
  2. They drop it into their wynntils/config/ folder
  3. They open config/wynnconfig-sync.json and paste the UUID of the sender into the source_uuid field
  4. They launch the game, the mod renames the file to the users UUID automatically

Launcher compatibility

Works with any launcher including Prism, MultiMC, ATLauncher and vanilla. The mod only needs to run once, after the rename it skips silently on every subsequent launch.

Notes

This mod is free to use and may be included in any modpack without permission.

This was a one-time project, regular updates should not be expected. It does what it needs to do and that's it!

Frequently Asked Questions

WynnConfigSync server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.

Is WynnConfigSync compatible with fabric?

WynnConfigSync officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with WynnConfigSync – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if WynnConfigSync consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
