General
Bonuses from Embrace of the Shale Spider and Blessing of Forgotten Kings can no longer stack.
Completing Archaeology projects will once again contribute to the guild achievement Making History once the player relogs.
The Orgrimmar portal to Mount Hyjal should now appear for players who flew directly into Hyjal to start questing, rather than take the Moonglade portal.
The old and busted Winter's Veil decorations in Brill have been disabled.
Paladin (Forums / Cataclysm Talent Calculator / Beta Skills/Talents)
Ancient Power now has a 30-second maximum duration and will properly be canceled when zoning or relogging.
Glyph of Seal of Insight now correctly increases healing done by Word of Glory and Light of Dawn while Seal of Insight is active.
Shaman (Forums / Cataclysm Talent Calculator / Beta Skills/Talents)
The Mana Tide Totem hotfix from yesterday has been reverted. The Mana Tide buff no longer stacks, as this had a major impact on encounter design.
Warlock (Forums / Cataclysm Talent Calculator / Beta Skills/Talents)
It is no longer possible to waste a Soulstone by attempting to use it on a dead target. The player will receive an Invalid Target error message at the completion of their channel. In a future patch, we intend this functionality to work correctly, allowing a Soulstone to be used to instantly resurrect a dead target.
