I can't find an answer to my specific problem but I see that everyone is talking about a CO taking responsibility for marking TBs as missing. My cache is up a steep hill and in the countryside so it isn't visited very often. However, I noted that some cachers were saying that my cache didn't have a TB in it. I went to check after a few months (in case it was waiting to be logged as moved) and sure enough there was no TB. I immediately marked it as missing and thought no more about it. I was recently looking at a list of my caches and noticed that the TB was back. There was a message which said "This is an automated message. ...the CO has moved TBKF9P to its last known location." This means that anyone climbing up there is going to be disappointed if they wanted the TB. Their message was automated so if I try to mark it as missing again it will just bounce back. Is there any way that I can remove it from my listing or do I just let it pretend to be there?
