If your solo in archons forge your walking in way too fast. Walk very slow up the stairs until you stay seeing xxxx is near in the bottom left. If that doesn't work and you get all the way to the top then go through the little passage in archons forge, get to the enemies kill 1 then walk back slowly into the forge and people WILL be there. It has NEVER not worked for me. Iv never been in there with less then 3 people, bungle should really explain this shit.
