Okay, guys, I need someone to explain Legion Archaeology dig sites and/or what my dumb ass is doing wrong. I've been trying for a couple months to do the This Side Up achievement but I have had Highmountain Digsites for the whole of the expansion. I leveled to 800 entirely on those.
I have had one Archaeology quest from Dalaran ever, and it was the one that sent me to Highmountain to complete the ghost moose. Which I did, some time ago. She's never offered me a new quest. The dig sites have never rotated to another zone that I have noticed, although I don't check literally every day.
My understanding is that the dig site locations are tied to the weekly quest. Does that mean the dig sites are supposed to rotate weekly? Does the quest come from someone other than the lady in Dalaran who gave me the first one? Do I actually need to pick up the quest for the dig sites to rotate? Am I just utterly broken or is it possible to get the same location a bunch of weeks in a row? (and if it is, it would be the same for everyone right? not just me?)
I feel like I am missing something, or an idiot, or both those things (probably) but I haven't been able to sufficiently find an explanation in any Arch guide or from friends who have bothered with it, as no one else seems to have this issue.
