The traffic in this section has grown quiet. Is it because people have finished and moved on or because the walkthrough is very effectively answering questions? For me it is the walkthrough. Alas, I didn't want to use it but after the mess in Act III I am so paranoid of goofing up Act IV too I am closely playing the game along with the walkthrough. The right thing of course would be to stop playing, wait for the next patch, and then to see what results others report as far as fixing problems from Act IV on. I can't do that now.
