Hello everyone. This evening I normally levelled my shammy in Zul'Drak, and after short relog strange things happened. I entered the game and saw.... hmm... I saw nothing.... completelly. No NPC, no players, no mobs. I spoke to my guildies and they said me to go to horde inn in Dalaran. So... I teleported to Dalaran, came to horde inn "Filthy animal", got some screenshots. In about 15 minutes I finally (Thank God!!) got teleported by game from da horde zone, and all NPC and players appeared. Can somebody tell what happened to my char, or maybe GM can contact with me ( i'm not a hacker, i was pretty scared of dat sutuation)?
Here are some screenshots as a proof.

Was the chat working whilst this occurred?
It looks like you lost the connection to the server to me; which means that no-one will enforce your location nor you will see anyone in the map, even though your new location will, in most cases, not be saved either.

From screenshots it looks like chat was working and he was able to put a totem so it looks like a phasing bug. It might be caused by some quest. There are a few things you can try: fly away from dalaran and go back, die and use spirit healer, abandon quests that you have taken recently, use unstuck feature on website (under services) or make a support ticket in game so a GM can check what's the problem.
