I would guess that someone in the several groups following behind me over a week's time may have it. On April 29th, someone picked up the only one in the cache. As when I was there, of the many listed, only two were actually there.
Some of those people were making multi state journeys, so it could take some time to see current logs for the trackables missing from the cache.
Keep the faith! And it has been resurrected once, it can rise again! 😉
