How to Host a Create'a Colony Server (Minecraft Modpack Guide)
Create'a Colony fuses Create's mechanical contraptions with MineColonies' NPC colony management on Forge 1.20.1 — you recruit colonists, assign jobs, and grow from a tiny outpost into a walled city, while Create's factories power the colony's industry and the colony harvests raw materials to feed those factories back. Hosting it well comes down to five things: the right RAM floor, a clean import, a watched first boot, a disciplined invite order, and backups before anything risky.
Start at a 6 GB RAM floor, not a guess. Create'a Colony's own listing recommends 6 GB minimum — that's the catalog's number for this exact pack, not a generic Forge modpack estimate, so treat it as the starting plan rather than something to round down from.
Import the modpack cleanly instead of guessing from a client export. Use a proper server-pack install path so Forge, Create, and MineColonies all land on matching versions — a mismatched client export is the fastest way to end up with colonists that won't path or machines that won't place.
Watch the console through the first boot. Create's kinetic network and MineColonies' colony/building registries both have to finish initializing before the world is safe to join — let the server reach a clean "Done" with no repeated capability or chunk errors before moving on.
Only invite players after that first clean startup. A pack this size needs one uninterrupted boot to prove both mod systems came up correctly; bringing players in during a rocky first load just multiplies the number of broken colonies and stuck contraptions you'll have to fix later.
Back up before every world import, loader update, or config change. Losing a world here doesn't just cost blocks — it costs hours of colonist recruitment, building upgrades, and the Create contraptions wired to feed them, so back up first every time.

CoalHost is built around modpack hosting, which makes Create'a Colony much less annoying to launch correctly.
