OK so when the game launched I was unable to get any achievements. I dismissed it as a bug that will be fixed quickly and continued playing. When the achievements were fixed I noticed achievements I should have had, such as "The Mad King's End", still were not there. At this point I didn't really care as I knew I was going to play through the game again. However when I started nightmare, I noticed if I had already picked up a journal the same journal would not drop again. This makes it impossible to complete the achievements associated with journals.
Any help would be greatly appreciated!
