Continuity mistake: Jack is shown wearing a security guard uniform throughout the entire infiltration of the launch party. When the party has been intercepted and Jack is exposed to everyone, he is still shown wearing the security guard uniform, but when the Horsemen are on the roof minutes later, Jack is suddenly back to wearing his leather jacket and T-shirt. Even if this is needed for the story and some time had passed between scenes for him to change, Jack was being chased by the FBI and was in a hurry to escape the building, so he would not have had anytime to change back, nor would he have risked wasting any time changing his clothes anyway. (00:24:35 - 00:25:30)
Continuity mistake: When Thaddeus is speaking to Dylan at the observatory, in the shot where Thaddeus says "You had let go of your thirty vendetta against me, for your Horsemen," Dylan is shown standing upright. In the next shot, his head is tilted to the left. (01:56:50)

Continuity mistake: When Dylan shows Natalie the drive containing all of Walter and Tressler's dealings, in the shot focusing on Natalie, he can be seen closing the fingers in his left hand into a fist. When the shot cuts to focus on Dylan, the fingers in his left hand are not closed into a fist. (01:52:55)
Continuity mistake: When Walter removes the card from the case after Daniel gives it to him, there is a close-up of the card in his hand. His hand is raised so that the palm of his hand is facing towards him. But in the next shot, his hand has turned around with the dorsal side of his hand facing towards him. (01:43:30)
Continuity mistake: When Daniel reveals the case containing the card to Walter, his fingers are all bent and spread apart. When the shot cuts, his fingers are straight and close together. (01:43:25)

Once the glass shatters, he has his left hand over his mouth (before beginning to lower it), and his right arm is lowered. When the shot cuts, he has both hands closed into fists and raised to his stomach. (01:12:22)
Continuity mistake: When Dylan finds the safe that his father used while in the magic shop, he has his right hand placed on the top of the safe. In the next shot, he opens the safe, but his forearm cannot be seen next to his face, like it was in the previous shot, indicating his hand is not on top of the safe. (01:05:48)
Continuity mistake: When Daniel is being given a pat down by the security guard, there is a shot where Lula is shown in the background and is the focus of the shot.

Continuity mistake: When Merritt sneezes, he says, "I must be allergic to something in here," and turns his head around to face one of the security guards. In the next shot, he is suddenly looking straight forwards at Allen. (00:57:23)
Audio problem: While the Horsemen are posing as doctors, Allen tells Lula it's actually topological quantum order after she asks him what gives. Then it cuts to a shot focusing on Lula where he says, "The emergence of quantum effects on a macroscopic level," but Allen's mouth doesn't appear to move during the shot. (00:55:45)
Continuity mistake: When Allen mentions an email that Lula sent, Daniel is shown turning his head to the right to look at Merritt and Jack in a moment of confusion. It then cuts to a closer shot of Daniel and Lula, where Daniel's head is suddenly turned to the left to face Lula. (00:55:07)
Continuity mistake: While on the plane, Dylan walks over to Thaddeus' seat to berate him. In the shots focusing on Thaddeus, Dylan has his hand placed on the top of the seat, but in the shots focusing on Dylan, his hand cannot be seen on the top of the seat. (00:51:05)
Continuity mistake: When Dylan and Thaddeus are first seen inside the plane, Thaddeus says, "I've had ample time to do some research and you know..." while leaning forward in the seat he is sitting in. When the shot cuts, he is leaning back against the seat. (00:49:25)

Continuity mistake: When Walter tells the Horsemen that the tube they were meant to jump down was twenty meters to their right, he tells them to sit down.

Answer: The only ones who knew the chip was fake were the Horsemen, no one else did. Walter did not know the chip was fake. The plan was to convince Walter that the chip was real so that they could lure him out of hiding with Walter attempting to kidnap and later kill them, and expose Walter to the public in doing so. They told the crowd after exposing Walter about the chip, because while it was a fake, they still had plans with it assuming it was real. If by "alert the FBI", you were referring to when Dylan gave the FBI director the evidence on Walter and Tressler, that was not the chip he gave to her, that was a hard drive containing all of Walter and Tressler's past dealings.
