I was playing several hours before when the game forces me to disconnect and quit. When I come back seconds ago, all my wearing gears are just gone. Now I get a sorcerer in hell naked 
Fingers crossed you get the items back… I had a very simular thing happen to me where all my sorc’s gear just was gone due to a bug… Well asked blizzard and they told me they would not restore the items… Really sad… What good is playing a game where at any moment you can lose all your time/progress/work? Sorry for your loss. I feel you… I really do…
Here is what blizz told me.
