Diablo III is currently offline in North America for patching, as a new version 1.0.6.13300 will be live when Blizzard's action/RPG returns. According to the Diablo III Website, this includes the first steps of some UI tweaking for Battle.net: "Patch 1.0.6 for Diablo III includes some of the data for this testing but will not impact your play experience. Similar testing-related data will be patched into World of Warcraft and StarCraft II in the future." The new version also adds a pair of bug fixes:

• Fixed an issue that allowed players to bypass the one-second trade timer when exchanging items via the Trade window
• Fixed an issue that caused the same item to occasionally drop for players using Threatening Shout with the Grim Harvest rune
