How to Host a Create Live 7 Server

Start with at least 6 GB of RAM. That's the recommended floor for Create Live 7's mod list on NeoForge 1.21.1 — Create's physics-heavy contraptions and train systems chew through memory fast once a few players are running rail lines at once, so don't start lower and hope to upgrade later.

Import the modpack directly rather than guessing from a client export. Create Live 7 is a curated Season 7 build with a specific mod and config set — pulling it in cleanly (server pack, not a manually zipped client folder) avoids missing server-side dependencies that trains and kinetic contraptions rely on.

Watch the console through first boot until it reaches a clean idle state. NeoForge mod loading for a pack this size can take a few minutes, and Create's registries (tracks, train signals, contraption assemblers) need to finish initializing before the world is safe to touch — don't assume it's ready just because the port opens.

Only invite players once that first clean startup has finished without errors. Letting people join mid-load on a Create pack risks desyncs in contraption assembly or signal blocks that are much harder to diagnose once a real rail network is built on top of them.

Take a backup before importing a world, updating the loader, or touching configs. A broken import on a Create Live 7 server doesn't just cost a chest of items — it risks an entire built-out train network and the factory lines that depend on it, which is a lot more painful to lose than a config mistake.
