Raids & Dungeons

Blackwing Lair

  • Several encounters in Blackwing Lair now cause the front gate to close, preventing players from zoning out or joining an in-progress battle.
  • The Razorgore encounter has been changed slightly to make it less "random". The spawning should be more consistent throughout the fight.
  • The timer for Vaelastrasz the Corrupt is now more persistent. You can no longer reset the one-hour time limit for beating him by leaving the instance. Also, Vaelastrasz the Corrupt will not respawn for 12 hours if he has not been beaten when the timer expires.
  • The drakes in Blackwing Lair will no longer leave the lab.



  • Increased the maximum number of sounds which can be played simultaneously. This will fix problems where some sounds could be dropped in very busy situations.
  • Fixed WoW Error Reporter so that it doesn't crash under Mac OS X 10.4 when trying to send an error report.
  • Worked around an issue where you would lose your Expose/Dashboard preferences if you crashed or asserted while in fullscreen mode on Mac OS X 10.4.
  • Fixed the "blockWidth", "srec", and "bitnum < m_numBits" assertions bugs that would crash the game.
  • Fixed a bug involving corpses near the player that could result in a crash ("BusError").
