I don't usually use my Bungie account but I figured if my info can help you resolve the Student of History glitch it might be worth it. I collected the last artifact I needed (the Memory of Radagast I believe) this past Tuesday (Nov. 15, 2016) late in the evening EST and attuned it on my main (a Warlock, if that helps). The progress tracker in the RoI book updated as complete and I unlocked it but no achievement popped. I've collected all of the artifacts on this one character; I haven't switched them over to other characters nor purchased any duplicates. All 8 fires in the Iron Temple are lit. I have not maxed out all of the artifacts (only about half are maxed) but I didn't think that was required. I was wondering if the order in which I obtained the artifacts mattered, or if it mattered that I couldn't buy one last week due to duplications in Tyra's offering. I didn't keep a list of which artifacts I obtained and when unfortunately. I can send pictures of the book, artifacts, unpopped achievement, etc if that would help. I'm assuming though that this is all server side so you can check status internally. If there's anything else I can do to help fix the glitch, let me know. Definitely looking forward to a fix for this soon. This achievement is the last one I need to finish Destiny. Thanks!
