SCP: Secret Laboratory Version Mismatch Fix
Patch day changes more than the client. The dedicated server, LabAPI or EXILED framework, and every plugin must be checked as one release chain.
Update in this order
- Announce maintenance and stop the server cleanly.
- Back up config, plugins and the current server directory.
- Update the dedicated-server build.
- Install compatible framework and plugin versions only after the server build is known.
- Start with no public players and inspect the log for load failures.
- Run one private round, then reopen the server.
Symptom map
| Symptom | Likely mismatch |
|---|---|
| Everyone is rejected | Client/server game build. |
| Stock server works, modded server fails | Framework or plugin. |
| Only one plugin is missing | Plugin dependency or API version. |
| Server starts but rounds misbehave | Gameplay config or plugin interaction. |
Never delete the whole config tree as a first response. Preserve it, boot a clean comparison copy, and restore only the settings that are known to work.
