On a side note: The way the game logic works, none of these three options are available until you have actually approached Rigard and spoken with Miranda. Before that, it's not possible to find Gwendy's farm or encounter the Outlaws in the forest. This is some lazy coding to avoid having to write a bunch of content variations.
As noted for Gwendy in particular, there's two triggers: you need to have high enough Rel with her (talk/work to increase it), and you need to approach her during a certain time window (early morning).
