Hey folks. This edition of OverAchiever was initially meant to cover archaeology achievements, but we've been getting so many questions on Insane in the Membrane and other problematic achievements that I decided to pre-empt the archaeology article. The Queue comments also tend to host a lot of achievement questions, so I want to answer as many of them as I can here. I apologize in advance to anyone who already knows some, most, or even all of the answers contained herein.
If you have a question concerning disappearing achievements, reappearing achievements, achievements that are being altered, or [insert issue du jour], hopefully you'll find the answer here. Additionally, there's some information on the Razzashi Hatchling that pet collectors might want to hear about (fair warning: It involves a Cataclysm spoiler related to Northern Stranglethorn content), in addition to notes on what's going on with the Shen'dralar, Dire Maul, Molten Core, and city reputation tabards. I ran both an Alliance and Horde character ragged on the beta to confirm everything in this article personally, and the information should be accurate as of the most recent beta patch.
