Sometimes the game assigns the Sages careers, in which case they will leave for work hours. When they have disinstantiated for work, a new Sage of that school appears, and steps in as a substitute while they are gone. You will need to cultivate a relationship with the substitute to be taught by them, as well. A Potion of Forced Friendship is the speedy work-around.
I can't believe I didn't think of this! Although, that's assuming that one has learned that before a sage gets a job. :/
