I have encountered two bugs (glitches?) today.

First one was about the fragments of the amulets and i can't find the piece that Gauldurson carries. Quest marker shows deep undergrounds, i searched it in the forum and saw many people has the same problem. Second one is about the Glories and Laments. I already cleaned out that place before and got the book before the quest started. Now, some guy from the College of Winterhold asked me to get it. I had the book with me but there was no dialogue line in speech. I went to the dungeon and found a chest that has a quest marker on top of it. I already took everything inside of the chest before starting the quest so... Marker is still there, book is still with me and the quest is with the.. i don't know. They are small bugs but second time in a day makes me angry of sorts. Seems like we shouldn't clear out any place before completing all quests.
