Rosetta camera glitch scuppers hi-res images

It seems a software problem on Rosetta switched of the hi-res camera so we will not be getting any higher definition images :(

New Scientist reports:

A glitch prevented the spacecraft from seeing the asteroid in even greater detail. OSIRIS's narrow-angle camera, which has a higher resolution, stopped collecting data minutes before the closest approach.

ESA scientists are still investigating why the instrument switched to this 'safe' mode, designed to protect the camera from injury.

Strangely, I can find nothing yet from ESA.
