Hi, tried to do Harbinger solo today but the final encounter wouldnt spawn. Had a quest marker saying follow the hawk that i couldnt seem to get too. I killed all the adds i could find along 2 diffrent paths and it didnt work I appreciate i might have missed an add or a checkpoint somewhere but surely it should still update when you get too the boss room? was very frustraiting to have to backtrack and I still was not sucessful. Any advice as to what i might have missed? Thanks Dan
