I just finished getting all of the Aether Currents in Sea of Clouds, all of the on foot ones and the ones from quests. So normally you would think I could fly right? Well according to my Aether Current checklist in game, I'm still missing a quest bound aether current, which as I've just said I have already done all the quests that give currents for the Sea of Clouds.

Ive checked online and according to the site, the quests required for Sea of Clouds are:
1. Flying the Nest
2. Sleepless in Ok' Zundu
3. Honoring the Past
4. Clipped Wings
5. Bolt Chain and Island

along with the 10 on foot currents.

If a GM would please contact me with some troubleshooting I would be appreciative.
