Teedubz: After disabling the cache, I have been back several times to hunt for the original container but the area seems to be getting cleared of foliage fairly frequently and I suspect it has been disposed of.
Unfortunately, I am currently not at home regularly, due to family illness, so maintaining an alternative container may be difficult. So it seems that, following the email from geocaching reviewers, just like our trackable, we have lost out to Muggles and this will need to be archived.
Apologies, especially to the owner of the trackable last listed within our cache.
