I never saw that before. But, what I did see near the entrance/exit of Ravenwood, is a tiny, moving, stream of whatever it is. I can guarantee that it's not water. When I first saw it, I was like "What type of moving stream is that?". I saw it a few weeks ago and it's still there (even in the Test Realm). It's found on the right side near the entrance/exit in Ravenwood. I even saw an invisible NPC in the Khrysalis Moon Cliffs somewhere near the Magic Bribge that leads to the Eclipse Tower. And in Unicorn Way, behind Rattlebones' Keep, there's a tree with glitched graphics. It's been since the graphics update came.
