Wrath of the Lich King Classic

When Engineering Tinker enchantments are activated, they now trigger their cooldown for all other engineering tinker enchantments that can be equipped in the same slot, as well as duplicates of their enchantment. This includes Mind Amplification Dish, Nitro Boosts, Hand-Mounted Pyro Rocket, Hyperspeed Accelerators, Personal Electromagnetic Pulse Generator, Flexweave Underlay, Frag Belt, and Springy Arachnoweave.

Master Elemental Shaper Krixix in Blackwing Lair is now guaranteed to drop the Goblin’s Guide to Elementium.

Fixed an issue that prevented two Shaman relics, Savage Gladiator’s Totem of the Third Wind and Hateful Gladiator’s Totem of the Third Wind, from functioning properly.

Various buffs gained from world events and quests such as Darkmoon Faire will now cancel when players enter any instance.

Shaman Sentry Totem no longer stops the player in mid air when cast.

Fixed an issue where players were unable to re-enter the Vault of Archavon instance to resurrect.

Fixed an issue with the achievement Share the Love in Heroic Gundrak, where use of player immunities such as Divine Intervention and Hand of Protection could prevent earning the achievement without leaving and re-entering the instance.

Fixed an issue with Strand of the Ancients where same-faction battleground teams disguised as the opposite faction would be sent to the wrong graveyard upon death.

Fixed an issue with the highest ranks of party and raid buffs where they were appearing incorrectly on unit frames during combat.
