Rembrandt Brown's license plate has no sticker tags when he is sucked into the wormhole. Later when the tornado comes he has them.
When Quinn goes to the college to tell Prof. Arturo about the wormhole he created, the chalkboard in the background has equations written on it, but after Prof. Arturo dismisses the class and walks out....there is nothing on the chalkboards.
When Quinn, Wade and Arturo are preparing to go on their first slide, Quinn is in the middle of the group. When they get sucked into the vortex, Wade is now in the middle.
When in the world where the Russians rule the Untited States, Arturo sees Lenin's monument and call him Nikolay Ilyich Ulyanov-Lenin. Lenin's first name was Vladimir.
In the phone booth, Lenin's name is misspelled "Lennin."
In the world where the US is Communist, The oath Rembrant swears in Court still uses "So help me God."
Since communism is antithetical to religion, it would likely be "under penalty of perjury."

In "The Guardian" the Sliders pass by a funeral in a San Francisco graveyard. But San Francisco has no operating cemeteries; the dead are interred in the city of Colma, further to the south.
The whole time that Quinn, Arturo, Wade, and Rembrandt are on the world where San Francisco is frozen you never see their breaths.
When Wade, Arturo and Quinn are walking through the frozen house there is the sound of wind howling, but the flames on their candles are steady.
When Rembrandt is walking out to his car to go to the ball game where he is to sing the anthem, the audio is of him practicing the anthem. His lips, however, are not moving to the words.
When Quinn, Wade and Arturo are looking off their porch at Rembrandt in the street, the San Francisco Bay Bridge and Yerba Buena Island and the San Francisco skyline are visible in the distance. But they're supposed to be in San Francisco at that moment. Such a view as shown is only visible in Oakland.
Quinn leaves his Midwestern-looking house (brick houses are scarce in earthquake country) and jogs through Golden Gate Park to the Berkeley campus, which is across the Bay. Rembrandt, in a hurry to get from Telegraph Hill to Candlestick Park (due south), drives west.
In the first visited alternate universe, people yell from their cars "Green means stop! Red means go!" yet car tail lights are still red and streets still have red stop signs.
In addition to sucking up Quinn, Wade, and Arturo, the moving tunnel also picks up Rembrandt and his car... but nothing else despite passing through many loose objects.
When the 2 KGB type men detain the questioning woman and drive off with her, one of the men first slams his door shut onto the long coat that he is wearing, and the car then drives off with it still hanging out of the bottom of the closed door.
