World of Warcraft v4.1.0a Patch

From v4.1.0 to v4.1.0a
Blizzard issued a new patch for World of Warcraft bringing their popular MMORPG to v4.1.0a (thanks: The Patches Scrolls). It fixes an issue that sometimes caused player to disconnect when zoning into another location. Also, the title Blackwing's Bane awarded for defeating Nefarian on Heroic difficulty is now selectable again by characters who have earned it.
