Grummelbaer_CVMA: After checking the site, I am very sad to say that the cache is gone. Judging by the high traffic of the area (who knew? It was deserted when I placed it!), I would say 1. A Muggle got it and 2. A Muggle would get any future versions of it.
Many apologies to the RVG group who sought so laboriously for this trove.
Further apologies to the owner of any lost bugs/coins.
Mea culpa. Mea maxima culpa.
