Cataclysm Deepholm is empty

Couple of days ago I saw some people saying that Deepholm is completly empty. I wanted to check it out and it sure is empty. No NPCs and no mobs. This could ruin the economy a bit and could ruin the leveling process for some people. The thing with Deepholm is that it's a important zone for Cataclysm because of Therazane reputation quest chain, rare spawn Aeonaxx, being able to farm cloth, herbs, mining nodes or leather and most of all because of leveling. I am not sure what happened to the zone because it "collapsed" a few days ago. I really hope you are working out the issue which caused this problem. I wish you the best of luck but we (Neltharion players) would really like an update on what happened and what are you trying to do to fix it. Thank you for all your answers in advance.
