How to Fix a MineColonies Official Server That Keeps Crashing
MineColonies' own building-generation system can occasionally throw a repeated error from a single block entity — and by default, that one broken piece of a colony can take the entire server down with it. One config flag changes that.
See the MineColonies Official pack page for sizing before you chase anything else.
1. A broken block entity crashing the whole server
Set removeErroringBlockEntities = true in the MineColonies config. When a specific block entity inside a colony building repeatedly errors — a common failure mode in a system that procedurally places this much custom content — this flag removes just that one entity and logs a warning, instead of letting the error take the whole server down.
This is the single highest-leverage fix for MineColonies-specific instability and costs nothing in lost colony progress.
2. CC Tweaked / Advanced Peripherals querying colony stats
If your server runs ComputerCraft automation that reads MineColonies stats via Advanced Peripherals, there's a reported crash path when that query executes during a chunk or player load. If automation scripts are running on the server, pause them temporarily to rule this specific interaction in or out.
3. Entering a world in creative mode
A specific reported case: the official pack crashing when a world is entered in creative mode. If that matches your situation exactly, it's a game-mode interaction worth isolating — try the same world in survival to confirm.
4. Removing conflicting mods
Beyond the specific causes above, general mod-conflict troubleshooting (removing recently added mods one at a time) is the standard fallback the community reports working when a crash doesn't match any of the three patterns above.
FAQ
What does removeErroringBlockEntities actually do?+
When a specific block entity inside a colony building throws a repeated error, the default behavior can take the whole server down with it. Setting removeErroringBlockEntities = true in the config tells the server to remove just that broken block entity and keep running, turning a server-killing bug into a logged warning instead.
Why does my server crash when a CC Tweaked script checks colony stats?+
Advanced Peripherals scripts that query MineColonies colony data have a reported crash path when that query fires during a chunk or player load. If you're running colony-stat automation via ComputerCraft/CC Tweaked, this is worth checking before assuming the crash is colony-side.
Does the MineColonies Official pack crash in creative mode specifically?+
There's a reported case of the pack crashing when entering a world in creative mode. If this matches what you're seeing, it points at a game-mode-specific interaction rather than anything about your colony or world size.
Host MineColonies with backups before any config change
CoalHost takes a backup before config edits like removeErroringBlockEntities, so a one-line fix never risks the colony you're fixing it for.
