Was your sdb not pinned or something? Maybe they could only get into that and not touch your UC.
If it was (with a new pin), then I'm not sure. I believe TNT did delete some of the dupes etc, but they did that earlier on. It would be odd if they did it now because they would realistically just be screwing users out of their items. I would consider maybe a ticket but like that's even a bit risky.
