To add a new tier to the game:

How to Install Tier Overflow Lib on Your Server

1

Order Satisfactory Server

Order a Satisfactory server with at least 4 GB RAM (6 GB recommended). For multiplayer: per 4 players.

Frequently Asked Questions

Tier Overflow Lib not working after update – what to do?

After a Satisfactory update, mods need to be updated. Check ficsit.app whether Tier Overflow Lib 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.

Tier Overflow Lib 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 Tier Overflow Lib v1.0.2 and the same SML. With Mado Hosting, Satisfactory servers run with 6 GB RAM for stable multiplayer performance.

Is Tier Overflow Lib compatible with other Satisfactory mods?

Tier Overflow Lib 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.
