The bug is not in the Shhh! cache. This log from the cache page on October 4 explains what happened to it:
I stopped by this afternon to get the coordinates of the CIK North TB, I had found both this cache & the TB before but have lost the coordinates. The TB is not in the cache anymore, it looks like a kid found the cache and took the TB. It was pretty hard to read his writing but he did say that he took the CIK TB. Maybe he was a cacher but the date was 9-27-05 and has not logged a visit to the cache.
