Can the PTC and CID in an 18650 have discontinuity from knocks?

I checked for discontinuities in a weldless 18650 box. There was a 0.041ms loss of signal when I dropped it from 35-40 cm straight onto the lid against wood... Do you think it could be the PTC / CID which could have vibrated and lost power? Because the CID contact area is quite small compared to the battery terminal so perhaps it can arc from sudden knocks?
