When Captain Janeway threatens to fire again at the planet's surface, Harry II touches the forcefield. Six seconds later, as Janeway speaks, he stands on his feet again and walks to the edge of the forcefield. He does not walk into it, he does not pass it. Neither is there a rule that says one character can't transition from kneeling to standing while off camera as another character speaks.
Chakotay can be seen holding a phaser when he went out with Seven and Harry. Seeing as the planet is supposed to be uninhibited there would be no need for weapons. It's almost as if he's targeting Harry because he knows he's a duplicate of the real Harry Kim.
When the Biomimetric copies of Tom and Harry are found they are both fully clothed. The two crewmen are copied through their DNA so clothes would not have been copied as well.
On the back of the environmental suits the away teams wear, the mic pack for each character can be clearly seen on the waist with a wire threaded through.
The demon planet is as hot as Venus, yet when Tom and Harry open the shuttle door, nothing inside melts from exposure to extreme heat. Atmospheric pressure, too, is high and should crush the pair as well.
Paris says the temperature on the planet is "500 degrees Kelvin." The Kelvin scale is not measured in degrees. The correct description would be "500 Kelvins."
