A trackable is normally “grabbed” because a cacher who finds a trackable in a cache is too impatient to allow it to be properly logged there, so instead of “retrieving” it from the cache he grabs it from the cacher. A very poor practice.
reb10, do you still have the trackable or have you placed it in another cache? If you have still got it you should grab it back and then place it in another cache. If you have already placed it but were a bit slow logging it then there is nothing else to be done.
