For now at least AI is really bad with beards. All the ones I've run into are anyway. Beards of any length--now that I've cut mine down some I don't have the same problems so they've improved or it's the length.
My bet is it still thinks it's the back of your head and weighs that too heavily.
That and eyes. It's always asking me to open my eyes wider.
So grow a beard and walk around with your eyes shut.
