Mama Murphy's "sight" predictions, broken?

[Justin_760]

So Ive noticed that every single time I go to Mama Murphy before a key story mission, she always give me ancient predictions, things that have happened days even weeks prior.

Early game spoilers ahead.

The foresight perk for kellog, the deactivation code for the courser, all the good ones that actually help are totally inaccessable because I go to her before those quests and she'll give me insight into an old quest, like the location of kelloggs house key even though kellogg has been dead for a week, thanks Mama Murphy!

How does the sight work? I thought she gave you tips on whatever part your at in main questline. Or is it totally random? I have a feeling its just broken, but if there is some esoteric method to this Id like to try and understand it.

If I am correct, the next parts of the main story don't auto-start every time. If so, you would need to start the relevant story quest before you go to Murphy for her Sight.
