Yeah, they moved a few of the currents around somewhere around patch 3.2-3.4. Anyone who already had them couldnt see where they were changed to. With that said, what i did for all of them(and all the SB ones) was put the aether compass on one of my hotbars. Using it gives you a direction and a distance. As you get closer it usually becomes apparent where they are. Easiest way would be to grab a friend with a 2 seater mount, you tell them the directions and they fly you straight there.
