Yeah, the strategy guide flowchart is all well and good if you haven't started the quest yet but doesn't cover the myriad of "What If" situations if you've completed various quest steps out of order. My first playthrough, I was able to complete the side quest but after going through the BoS steps first on my current playthrough, I can't seem to get ED-E to trigger the 2nd log by using all of the steps (Ignacio, ARCHIMEDES terminal, Michael Angelo Medical Check, Arcade Gannon dialog).
