How to Host a Medival, Magic & Tech Server

Start the server on at least 6 GB of RAM — that's the floor Medival, Magic & Tech needs to load its NeoForge 1.21.1 mod set (medieval building mods, layered magic systems, and industrial-age tech mods) without stalling during world generation.

Import the modpack directly from its official release file instead of rebuilding it from a client instance export — a clean import keeps the medieval, magic, and tech mod layers in the exact order the pack author intended, which avoids the conflicts manual copying tends to introduce.

Watch the console through the first boot and let it finish entirely before doing anything else — this pack loads three distinct mod layers in sequence (medieval structure/building mods, then magic systems, then tech/automation mods), and a server that looks 'done' after the medieval layer loads is often still mid-way through initializing the magic and tech registries.

Only invite players once you've confirmed a full clean startup with no repeated errors in the log — Medival, Magic & Tech's progression arc depends on players reaching mod systems in order, and a server that crashes mid-boot can corrupt the early-game state before anyone even gets through the medieval tier.

Take a full world backup before importing an existing world, updating the NeoForge loader, or changing any mod configs — a failed update here can wipe out a group's progression across all three tiers: the medieval base, the magic system unlocks, and whatever tech automation they've built on top.
