It was then either retrieved by the following visitor on July 4th, 2016 or went missing when the cache was confirmed muggled by the following visitor on July 6th, 2016.
Several of the following cache visitors mention that the cache is all empty. Not even a log book to sign.
A visitor on July 14th, 2016 mentions in the cache log entry that the TB is missing.
Until eventually found, should this trackable be marked as missing by either its owner OR by the current cache owner by visiting the trackable's page and select "Mark as missing" on the right-hand side of the page. By doing so, new visitors won't think it might still be present in cache. It will still continue its journey once it re-appears.
