In the wiki, you could find the information, that if first pre event of Arah is bugged, you should ‘Lure a Veteran Risen Giant’ , but this way doesn’t work.
I had this problem yesterday, when this bug appeared and I didn’t know what should I and others, who followed me do. And I checked the wiki and we tried pull Veteran Giant to the Pact’s forces, but his way is very short. And we came up with an idea: “maybe Champion could help us” and we did it. When he was nearby the Pact’s forces, they attacked him and after when we killed champion with them, they moved to the next camp.
So if you will have a same problem like I had yesterday, lets try this way!
I change a note in the wiki as well.
So you don’t need to wait to the server reset now.
