Patch 1.6.1

Patch 1.6.1 was released on August 2, 2005.

General

 * Spell casting is no longer interrupted when leaving combat.

Warriors

 * Improved Shield Block - Fixed a bug where Rank 3 of the talent was not granting the extra block.
 * Bloodthirst - Damage bonus increased to 40% of attack power.

Items

 * The Oil of Immolation effect is no longer affected by bonuses to spell damage from items.

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.

Maraudon

 * Lowered experience values for Creeping Sludge.

Macs

 * 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").
