Is Insane removed by gaining a skill from a completed quest or pilgrimage, or only by an Encounter?

Question

Accepted Answer

Only by gaining a skill from an Encounter. Skills from completed quests or pilgrimages do not clear Insane. A Talent skill from the story track is not an encounter reward either, though one poster argues it clears the status.
