Frequently Asked Questions
Tower Defense (Alpha) not working after update – what to do?
After a Satisfactory update, mods need to be updated. Check ficsit.app whether Tower Defense (Alpha) 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.
Tower Defense (Alpha) 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 Tower Defense (Alpha) v1.0.7 and the same SML. With Mado Hosting, Satisfactory servers run with 6 GB RAM for stable multiplayer performance.
Is Tower Defense (Alpha) compatible with other Satisfactory mods?
Tower Defense (Alpha) 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.
