Things are getting closer to being ready. The problem with bugs and glitch's is that when you implement a fix it can sometimes allow a new bug or glitch in something else,
Beta tester's may be on the world but its not so much fun testing... re testing.. and testing again has to be performed every time a change is made. No ones getting to have an advantage by having early access to the world.
No one wants to go on the server only to have it down again after 4 hours because someone found a way to create 10,000 diamonds and can get Opped at a whim. While that may be an exaggeration of the issues, No one wants to play on a broken server, and no one wants hourly restarts, and no one wants to have random issues like.. All there money is suddenly gone..
Little things pop up. and sometimes it can take awhile to figure out "Exactly" why its happening.
The server is still here, the map and its backup are still intact. No ones loosing anything. But we will all gain allot when its finished.
