How to Host a Marvins Minecolony Pack Server (NeoForge 1.21.1)
Marvins Minecolony Pack is a well-maintained MineColonies-focused server pack built on NeoForge 1.21.1, where players build and manage an NPC colony with assigned worker roles. It adds just enough supporting mods to keep that experience coherent, plus quest guidance that teaches the MineColonies systems new players usually miss — so getting the setup right from the first boot matters more than usual.
Start with at least 6 GB of RAM — that's the recommended floor for Marvins Minecolony Pack's NeoForge 1.21.1 base, and it gives MineColonies room to track colony buildings, worker pathfinding, and quest state without stuttering.
Import the modpack through a proper modpack install flow rather than guessing at the mod list from a friend's client export — Marvins Minecolony Pack bundles a specific set of supporting mods around MineColonies, and a mismatched version can break colony building templates or quest triggers on NeoForge 1.21.1.
Watch the server console through the first full boot before touching anything else. MineColonies needs to register its building schematics, worker AI, and the pack's quest guidance on startup — let it finish loading cleanly with no repeating errors before you consider the server ready.
Only invite players after that first boot has completed cleanly. Letting people join mid-boot is the fastest way to end up with half-initialized colonies or workers stuck without jobs.
Take a backup before importing an existing world, updating the NeoForge loader, or changing any MineColonies configs. A bad import or config change can wipe out hours of colony progress — assigned workers, built-up colonist levels, and completed quest lines — so back up first.
