Apologies. As Rongway described, it is normal for the Aether Currents Log to show no information when you until you collect one Aether current somehow. Somehow I was not aware of this. A;so the one invisible Aether current I described was behaving normally when I checked today, it was simply above the spot where I thought it was. (The Aether compass only describes horizontal distance apparently.) I misunderstood certain details of the game, and couldn't find any information online and assumed there was something horribly wrong. Sorry.

Please consider this issue closed. Bug is not a Bug.
