Troubleshooting

Plugin does not load: verify server/Java compatibility and inspect the first startup exception. Guide or command missing: verify command permissions and check /plugins plus /sf versions. Item locked: check Items.yml, Researches.yml and permissions.yml. Machine stopped: verify recipe/setup, energy, chunk loading and stored block data.

Addon failure: update it or remove it temporarily, then restart; never /reload. Performance issue: use /sf timings and a server profiler, noting world and machine coordinates. Data loss/corruption: stop the server and restore both plugin files and data-storage from the same backup snapshot.
