WE100 (or one of its variants) sent to me to Labyrinthian to find an enchanted bow and claimed it was guarded by Morokei. However, it turns out that the bow was actually in a chest in Lost Valkygg (Cell: ValkyggOrigin, RefID: 00080A4C) and guarded by a Draugr Deathlord. If the note had been accurate, the bow would have been in the cell named 'LabyrinthianBossArena' and in the boss chest with RefID 000CA310.

This may not be something that can be fixed due to the complexity of the way everything is set up. Despite supposedly being separate dungeons, the various cells and sections all appear to be part of the same worldspace (LabyrinthianWorld). I don't know if this is why the note was completely wrong or not.
