This trackable was unfortunately not seen in cache "Humble Bee - Stockholm starting cache" when I (re-)visited 03/20/2020 to check for trackables: None found, which means that ART.4.EVER, TB5JE6M, and ... were missing. Most of the log book has broken into say 50 small papers in no time order, so it didn't give me any further information.
TB owner and cache owner, please consider to move the traveller to Unknown Location (Mark Item Missing) if it doesn't show up soon.
