not checked yet did they fix her level bug? ie when you recruit her she stays at a low level
All the followers have that bug (I think) and a work-around is using the Wabbajack. Take them into the wilderness, save game (as the Wabbajack can instantly kill), dismiss them, blast them with Wabbajack so they transform into another being (chicken, dremora, mudcrab, ect.). When they respawn, they will be re-leveled. Also, removing the stuff you gave them might be a good idea, I'm not sure if they will still have it when they respawn, as I have never actually tested this, nor did I discover it. Just passing along what I've heard.
