My aether currents for Rak'Tika Greatwood says I'm still missing a quest, but I'm unable to find what that quest even is. I've found all the quests that people list as being aether current quests (Stand on Ceremony, Suit Up, The Great Deceiver, What We Do for Family, The Burden of Knowledge), but it's still listed as missing one. The only blue quests I have available are "Seeing Eye to Eye" and "Snake the Lead", neither of which seem to reward aether currents.

Am I missing an obvious quest, or is this a glitch?
