Was flying back to base on my wyvren when I hit this spot that dis-mounted. Its kind of like a wall, or like an invisible river. I fell and they wyvren floated up. This was roughly at 41/74. I had an admin help me try to find the wyvren, but it's gone (it is what it is, i can get another). It also sends server admins straight up. I'm sure that this area has been reported, but I wanted to make sure.
