Great read, thanks for sharing!
You may just have to wait it out, they eat when they are ready to eat, but I wouldn't stop trying different methods to coax her. Have you tried changing the substrate (this worked for me for one snake)? Removing her hide? Sterilizing her tub/getting rid of the sent to make it seem like a new environment (this also worked for me)? I personally have better feeding success rates when I offer a small live rat or mouse, and feed in the evenings/dimly lit room.
