Deliberate mistake: Wade and Quinn go to the Top Hat Club. We see a line of people waiting to get in. After they are in the club a while, leave in a taxi, go to the park to meet Rembrandt and Arturo, discuss some things, talk to some passersby, and go back to the Top Hat. We again see a line waiting to get in. It is the same line with the same people in the same place as way earlier. It is a repeated shot of the previous queue from when they went there the first time.

1 deliberate mistake in Love Gods
Other mistake: The Sliders discover the reverse-time issue when they notice that the clock on the wall is backward. However, in other shots, clocks look normal. Look carefully at the clocks on the judge's desk as the camera pans by.
Just Say Yes - S4-E7
Agent Lowell: That's Mallory all right. Busted twice for non-possession. Jumped bail a year ago and ran off to Mexico.
Damon: I heard he died of an under-dose.
Agent Lowell: Same here. I guess we were wrong, huh? It's a safe bet Mallory snuck back into the country to spread more of his anti-drug propaganda. A guy like that shouldn't be on the street.
Trivia: On the equation on Quinn's chalkboard, T squared ("T2") appears in several places, a nod to Tracey Torme, Co-director of the series.
