We recently had a TB logged into one of our caches and then it disapeared. The next few logs said no TB in cache , so we read the logs and notified the owner of the bug that it might be MIA. After carefully reading over the logs, we sent email to one of the newest cachers (2 finds) and asked if they understood about TB's and if they had picked one up at our cache. It wasa soon after that the TB was logged out and on its way again. Moral, not only the owner of the TB can help but good cache maint. will also help.
