By the sound of it, something went wrong with the auto cockpit navigation computer and if that's the case, the pilots wouldn't be aware that anything was going wrong until it was too late.

but surely Auto cockpit computer or not, the pilots and crew and passengers would have felt the plane descending and wondered why ?

So the Pilots would have disengaged this computer and flown the plane manually and they would have reported the fault straight away.
