How to Host a Modern Skyblock 3 Server
Hosting Modern Skyblock 3: Departed cleanly is less about some hidden command and more about doing the obvious things in the right order: enough RAM, a proper modpack flow, a clean first boot and backups before anyone pushes further into the 15+ chapter narrative than it's been tested.
Start with 6 GB unless this is a very small server — Modern Skyblock 3's own recommended floor.
Use a proper modpack import flow instead of guessing from a client export.
Watch the first boot logs until the server finishes loading on Forge 1.12.2 and the void starter platform generates cleanly.
Invite players only after the first clean startup.
Take a backup before world imports, updates or config changes — losing questline progress across 15+ chapters is a bad night.

CoalHost is built around modpack hosting, which makes Modern Skyblock 3 much less annoying to launch correctly.
