Point 1 is referring to Audra (see walkthrough)
Point 2 has only a window of one day, if you don't hack it then when the choice dialogue comes up in the morning then Nimhe picks it up and the opportunity is gone. It will not block anything though as it is a bonus item
ah, not the title i was expecting for something constantly called "the walkthrough."
having read it, though, the problem remains. the walkthrough simply says to "free slaves." where is this an option? does it mean "eject slave cargo?"
i also glanced through the nimhe section, and the "hacked door" thing i'm missing did not jump out at me.
