Hello, I was in the Nagrand arena. And my screen went black. After the arena ended I closed the game. Then I relaunched it. But my character is still in the arena. When I try to connect it tells me that "The world server is down". I can no longer connect any of my 3 characters on "Frostmourn" but I can still on other server of "Warmane". I tried to unlock my character who was teleported to "Dalaran". But I still can't play. Can you help me please ?
