Guys, our servers have been hacked twice today, the core staff is aware of this and are doing there best too figure out what and who is going on. If people keep hacking our server please notify an admin and be patient. We are trying to find out who it is through a process of elimination. If you get kicked from one of our servers and you are not the hacker just stay out of the server for a bit and come back when its restarted or things are under control. 
 
Information that can help us!
- Recent unknown players that connect before the hack
- Players not being affected by the hack
- People who are being funny
- What exactly is happening
 
 
Please be carefull on who you accuse. And be patient with the AW Staff.
