How to Host a City Life: Lumina City Server (Forge 1.19.2 Setup Guide)

Start with at least 5 GB of RAM allocated to the server. City Life: Lumina City runs Forge 1.19.2 with vehicle, transit, job, and economy mods layered over the base game, and Lumina City's districts and civic structures need that headroom to generate and stay responsive as players explore the city.

Import the modpack directly from its official package instead of rebuilding it from a client export — City Life: Lumina City's job, transit, and economy mods depend on matching server-side configs, and guessing them from a client install is how car ownership, bus routes, or payroll systems end up broken.

Watch the console through first boot until Forge finishes loading every mod and the server reaches "Done" — Lumina City's economy and transit systems register shops, routes, and job stations during startup, and a server that looks "up" before that finishes will show players an empty or broken city.

Only invite players once that first clean boot is confirmed. Letting people log in mid-generation is the fastest way to have someone buy a car or start a job before the city's economy data has finished initializing.

Take a backup before importing a world, updating Forge, or changing job/economy configs. If the business, car ownership, or transit data gets corrupted mid-update, players lose real progress — houses, vehicles, and job standing — that can't be rebuilt by hand.
