monsters levatating and disappearing

[shinjaon]

I'm not a new player, played during the first and second beta phases, but it has been a while since I've played and I have come back to it. One thing that I noticed is that enemies will rise above your head or disappear. This has to be a glitch because if this is some stupid trick that these guys can pull it is pretty dumb. Any thoughts on this because I don't remember this happening during beta. Then again, all I remember from beta was really bad FPS and walking on the sea bed floor and under the islands. Took me 5 minutes to walk across the dock once during beta.
