Lately I have been doing a lot of archaeology, in order to get 100% completion in the achievement professions tab.
All goes fine, but then I noticed a big thorn in my side.
For the Mogu solves, I just need 3 Mogu Coins and 2 Bone Whips.
For the Pandaren solves, I need ~7 solves for 5 projects. But the Twin Stein Set.. That damn set. I have a grand total of 6 solves.
For the last 5 days, I have been doing several solves every day, but haven't seen the Twin Stein Set once.
Funny, I also had every other Collector achievement before I even got 10 Twin Stein Sets. I believe I was at around 40 to 50 solves on most artifacts before I got 20 of those things.
