How to Update a MineColonies Server Safely
MineColonies updates go wrong when its sub-mods — Structurize, BlockUI, Domum Ornamentum — get updated separately instead of together. Backup first, update the whole family at once, and verify before reopening.
Start with a restore point
Back up the world and colony data before touching anything — colonies represent real build time.
Update the whole mod family together
- Download MineColonies and its required sub-mods — Structurize, BlockUI, Domum Ornamentum — from the same release cycle, never update just one.
- Match the NeoForge version to what the new MineColonies release specifies.
- Keep custom structure files backed up separately before any update that touches the schematic system.
Verify before you reopen the server
Let the world load fully and check that existing colonies' work orders resume normally before inviting players back.
FAQ
Can I update just the MineColonies mod and leave its sub-mods alone?+
No — Structurize, BlockUI and Domum Ornamentum are tightly version-matched to MineColonies itself. Update them together.
What's the biggest risk when updating MineColonies?+
A sub-mod version mismatch, which is the single most common crash cause after a manual update.
Should I back up anything besides the world?+
Any custom structure or schematic files you've added — they can be overwritten or orphaned by an update.
