This little guy magically was dropped in one of my caches and then I noticed through the logs that he was "discovered" in another one. I grabbed him this morning to get him back on track. My experience is that, as soon as the tb becomes disconnected from the caches, they have a tendency to disappear. Will drop him somewhere else soon and get his log going again. Perhaps its not just "muggles" who need the education. 🙂
