I can't see most NPC in Pandaria

I have just reached lvl 85 and travelled to Pandaria territory. As soon as I got there I couldnt see anyone on my party and most of NPC are gone: All NPC that hand quests, sell or interact with players with the exception of a few that hang around.
I can collect herbs and walk around with no problem and see a few mobs, but there is almost no one in the villages. I tried to relog and change settings. I would appreciate the help with this problem. Thank you in advance.

Open a ticket in-game, a GM should help you.

I tried contacting GM in game and no one responded... The problem persists and friends are trying to help me but nothing works
