In the mid-1980s, there were two episodes missing, episode 2 and 7 of season 2. So Aad van Toor re-edited the series, to make the story work without those episodes. All reruns, videos and DVDs until 2004 are missing about three episodes because of this. (Aad had to delete about one episode of material to remove any references to the missing episodes.) One of the two missing episodes was rediscovered in 2004 (episode 2). It was put back in again, together with some of the material referring to it.
