I have to agree with Katherine. It doesn't strike me as terribly unusual that they could overlook a basket of figs and some limestone fragments especially after you had found the undisturbed gold coffin pf the boy king. For instance a number of year ago I saw a film on an excavation that Carter had made of another tomb in the VOK the entry in his book was the tomb was empty, or that there was nothing of interest in it. The tomb was reexcavated and they found a mummy and quite a bit of stuff in it. Of course it was inconsequential to Tut's tomb and it was a non-royal tomb so Carter's evaluation of the tomb as 'inconsequential' was correct for the time. iirc the tomb the mummy and everything in it was placed in plywood boxes made in situ and left there because there wasn't room at the cairo museum for all of it.
