I met this issue - I found TB in cache where it shouldn't be. So I created a log with "grabb" option but there wasn't possibility to log the location. Then I found that it shoudl be possible to log also the location as somebody in the history of this TB did it. So I, unfortunately, deleted my log and log it again - but this time only Discover option there...
I hope I will fix the TB history this weekend placing it quite near to place where I found it and correcly logging it there, but it would be nice to know where I did a mistake when doing the first log.
