How to Host The NotJen Pack Server (Forge 1.19.2 Setup Guide)

Start with at least 6GB of RAM dedicated to the modpack — that's the floor The NotJen Pack's own recommendation lands on since it layers extra boss fights and tougher mob AI on top of a near-vanilla Forge 1.19.2 base; drop much below that and the added combat systems start chugging during fights.

Import the official modpack file directly through CoalHost's panel instead of trying to recreate the pack by hand from a client export — The NotJen Pack's balance comes from Forge mods tuned together, and installing from the real server pack keeps every boss and mob tweak wired up correctly from the first boot.

Watch the console through the first boot until the world finishes generating and the loading screen clears. Because this pack stays close to vanilla, a clean boot looks almost like stock Minecraft, so any mod-loading errors or missing dependency warnings in the log stand out clearly and are worth catching before anyone logs in.

Only open the server to players once that first boot has completed without errors — spawning players into a world while the boss and mob-difficulty mods are still mid-initialization is the easiest way to trigger a crash in the first five minutes.

Take a backup before importing an existing world, updating Forge or any mod, or editing the bundled configs. The NotJen Pack's harder mobs and bosses make survival progress fragile, and a bad update can wipe out hours of hard-won gear and base-building in one restart.
