Continuity mistake: In the episode that aired in the UK on the 10th March, 2004, Harold was almost run over when he was on a walk. The Harold on the road was mostly bald and wasn't wearing glasses. Ian Smith that plays Harold has most of his hair and Harold was wearing his glasses in the next shot.
Continuity mistake: Tahnee and Nina found various copied pictures of Harold with different crazy hair styles in the trash at Lassiters. When Harold found the original images, there were many pictures of the people from Ramsay street, but only one of Harold.
Continuity mistake: Back when Nina was recieving text messages from Taj, her phone used to ring when she got a text, but sometimes it made a text alert noise. She also read one of the messages before it came on the screen (the shot was of the screen).
Answer: If my memory serves me correct, there have been no others like that.
