The Serpent's Lair (3) - S2-E1
Continuity mistake: When Daniel is shot by a Jaffa staff weapon, the hole in his jacket is very visible. When Daniel comes out healed from the sarcophagus, it has also mended his jacket, but it's shown in other episodes that it doesn't repair clothing.
Continuity mistake: You hear "chevron four encoded" but the third chevron lights up.
Continuity mistake: When Carter gets stuck in the elevator, she's on level 22. Every time the level changed, you can hear a beeping noise and there's no noise after we see 22. But from outside, the doors say 28. It wasn't a cut away shot either.
Continuity mistake: When O'Neill and Carter arrive at Washington, Carter says "Don't worry, Sir. These were my old stomping grounds." O'Neill replies with "I'm sorry to hear that." But later when the reporter approaches O'Neill in the bar the recording says "My condolences."
Touchstone - S2-E14
Continuity mistake: The Stargate on the Weather Controlled Planet has the Earth symbol (Similar to Å) on it, while it should be exclusive to Earth. (00:02:18)
Continuity mistake: In an early scene "Ma'chello" is lying in the infirmary with a oxygen mask on, it cuts to Frasier and O'Neill talking about him, then cuts back and "Ma'chello" now has nose tubes.
Answer: While the series was undeniably successful, filming it is a long process, taking many months of often long days. Anderson, after several years of doing this, wished to spend more time with his young daughter, who he felt he was neglecting, and requested that his role in the series be scaled back. Ultimately, he decided to leave the main cast altogether and only make occasional guest appearances.
