The issues appear to be resolved. Windows forced a reset of the server PC while Bungee and I were out doing some Christmas shopping. It force-closed the servers. The Island and SE, as well as the test server, came through alright but The Center was corrupted.
I believe I was able to get everything running properly again (after some very strange side-effects!), so please let me know if you are seeing any issues.
