How to Update a Seablock Server | Safer 2026 Guide
Seablock updates are routine on Forge 1.12.2, but the pack's long GregTech-style production chains make a backup and a couple of config re-checks worth the extra few minutes.
Already crash-looping? See the Seablock crash-fix guide, or the Seablock pack page.
1. Back up before updating
Water-chemistry production chains and the ocean starter platform represent real time investment. Take a full world backup before touching the pack files.
2. Install the matching Forge 1.12.2 server pack
- Download the server pack for your target version from CurseForge — not the client pack.
- Shut the server down with the stop command before swapping files.
- Install into a clean mods folder rather than layering the new version over the old one.
3. Re-check FoamFix and tick-watchdog settings
If you'd previously disabled FoamFix or adjusted tick-timeout settings to resolve a crash, confirm those changes survived the update rather than assuming a fresh server pack carries them over automatically.
4. Match client and server versions
Players need the exact same pack version as the server — a mismatch after an update shows up as join failures that are easy to misattribute to something else.
FAQ
Will updating break my ocean production chains?+
It shouldn't directly, but long GregTech-style processing chains are sensitive to version drift mid-save in a way lighter packs aren't. A backup before updating is the real protection, not an optional step.
Do I need to reconfigure FoamFix after updating?+
Check it either way. If you disabled FoamFix to resolve a crash before updating, confirm that setting survived the update rather than assuming it carried over automatically.
What Minecraft version does Seablock run on?+
Forge 1.12.2. This has stayed consistent across the pack's updates, so a routine update here is a patch within that version, not a Minecraft version jump.
Update Seablock without losing production-chain progress
CoalHost keeps automatic backups ahead of every update and the right Forge 1.12.2 stack for Seablock in place by default.
