How to Host a Mustard Virus Server
Hosting Mustard Virus 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 the next outbreak wave.
Start with 8 GB unless this is a very small server — the recommended floor for a smooth multiplayer experience.
Use a proper modpack import flow instead of guessing from a client export.
Watch the first boot logs until the server finishes loading and the zombie-apocalypse world generates.
Invite players only after the first clean startup.
Take a backup before world imports, Forge updates or config changes — survival progress is slow to rebuild.
Use a cleaner Mustard Virus path
CoalHost is built around modpack hosting, which makes Mustard Virus much less annoying to launch correctly.
