My original question was intended to be more like "If somebody else's TB or coin is in MY cache and is removed and not logged what should I do?" I did mark a coin "missing" after 2 months because people saw the icon and kept coming to look for it. And that was the only way I could find to get rid of the icon. Finally it was logged and moved and the fact that I had marked it "missing" didn't seem to bother the process any.

And my TB that someone had for 5 months just surfaced again. Go Mikey!
