I am currently stuck on a series of quests, the Ouroboros Research quests. I have been able to complete some of them, they put location markers on the overworld and it was a simple pick up. However I am stuck on missions 1,2,4. The translation guide for quest one says that the notes are at the World Tree on Yuria, however no marker shows up for me. I've searched around and I can't find them. Similarly quests 2 and 4 have me going to Ratatosk cave and Mimir cave but no markers and I can't find the notes. Has anyone else had this problem?
