Frequently Asked Questions

Satisfactory Mod Loader not working after update – what to do?

After a Satisfactory update, mods need to be updated. Check ficsit.app whether Satisfactory Mod Loader has been updated for the new game version. With Mado Hosting: open the mod manager and click "Update All". If the mod hasn't been updated yet, temporarily remove it so the server starts.

Satisfactory Mod Loader causing crashes in multiplayer – solution

Most common cause: all players must have exactly the same mod version installed. Check server logs for "ModMismatch" or "Version Conflict". Ensure all players use Satisfactory Mod Loader v3.12.0 and the same SML. With Mado Hosting, Satisfactory servers run with 6 GB RAM for stable multiplayer performance.

Is Satisfactory Mod Loader compatible with other Satisfactory mods?

Satisfactory Mod Loader uses the Satisfactory Mod Loader (SML). Generally, SML-based mods are cross-compatible, but mods modifying the same game systems can cause conflicts. Test new mod combinations on a backup save. The Mado dashboard automatically detects known conflicts and warns you.
