Hi everyone. I have some issues about the Draenor questline. I did all the starting quests in Draenor around the Dark Portal, also I did a last quest when I escaped that jungle and I came to Shadowmoon Valley. I took a first quest there but I could not to do it because it was bugged. So I try to abandoned it but I could not take it back. So I tried to go to Stormwind and than back to Draenor. And here is the main issue. I can not get to Shadowmoon Valley anymore, I can not take quests there I am stuck near in the Dark Portal area. Please I will appreciate If you will respond somehow, or you will find a solution. Thanks
