Here is a pretty big bug with orgrimmar auction house for world of warcraft patch 4.0.3. This bug basically requires you first of all to have a large mount and that mount needs to be flying mount in the game. With this bug you first need to fly into the wall. Near the auction house as shown in the video. From there you then find a small crack. Then you keep on trying to summon your mount again. It will take you a few times to get your mount properly taken out in the game.
If you have done it correctly it will bug you on the other side of the wall. Then you just need to start trying to move around. After a few tries it will allow you to actually bug out under the game world. From there you can start traveling around orgrimmar. Then when you want just dismount and you will now be able to spawn back above ground in the game. Its a great feature for players that want to get around the game world easily with this world of warcraft bug for wow cataclysm. Keep in mind do not use this orgrimmar wow bug in the game around any game world mods as they may ban you or give you at the very least an account suspension for using it.
