At the beginning, the main characters are wearing clothes they don't receive until Summer of Love (1995), and are trapped atop a building by the oncoming flood implied at the end of that episode. This is probably because of an error in syndication order, meaning this would have to chronologically take place after "Summer of Love," despite of its earlier air date.
When Professor Arturo talks to the soldier in the forest, the position of Arturo's hands continue to change between cuts. They are in his pockets when he's facing the camera, and behind his back in the reverse shot.
During Summer of Love (1995) Rembrandt gets a letter dated January 1995. During this episode, Wade picks up a newspaper dated February 1995, and the group later has newspapers from March 1995. However, all of these events are supposed to take place over approximately a week.
At the end of Summer of Love (1995), the Sliders land on a world for 48 minutes. It's night. This episode begins with them still on that world with the 48 minutes almost up, and it's now broad daylight.
At the end of the episode, Professor Arturo gives Prince Harold a piece of paper and says "here's the rest of the Bill of Rights, use it wisely." When Harold reads it, he begins, "We hold these truths to be self-evident...." This is the opening line to the preamble of The Declaration of Independence and is not found anywhere in the US Constitution or Bill of Rights.
When the Sliders are seen on the world with the flooded downtown San Francisco, the Golden Gate Bridge can still be seen in the background as they are clinging to the top of one of the highest buildings in the city. The bridge would never survive a wave that was that tall.
When Quinn and Wade have a personal conversation about Rebecca, there is a shot in which you see the camera from the other angle. When Wade says "she tried to kill all of us", you can see the lens and the cameraman's hand coming from behind a piece of set decoration.
The flag used for the "British States of America" has 13 stripes. This seems illogical, given that the 13 stripes and stars of the popularly called "Betsy Ross Flag" is primarily assumed to have been ordered by revolutionary rebels, including George Washington. Why would the Empire preserve the designs of a rebel they publicly executed?
When the group first enter their hotel room, the boom mic dips down from the ceiling.
