The Monster in the Closet - S11-E13
Continuity mistake: Karen cuts her hand in the interrogation room. Between camera angles the amount of blood changes instantly. (00:24:15)
The Fight in the Fixer - S11-E15
Continuity mistake: When Bones is discussing Angela's cut off point for reconstructions, her hand goes from open and facing to the floor to pointing with one finger at the screen.
The Fight in the Fixer - S11-E15
Revealing mistake: Hodgins turns the furnace off at the start. However the yellow light from the flames in the tunnels disappears before he turns the furnace off.
The Secret in the Service - S11-E17
Visible crew/equipment: A potential editing oversight can be found as Booth and Brennan are entering the shooting range by watching the space under the rifle of the third shooter. The gas can be seen coming from the spray can to the shooter's right, not the barrel of the rifle. (00:19:05)
The Secret in the Service - S11-E17
Plot hole: The chute is supposed to be so narrow that it injured the Secret Service agent's shoulder, but is wide enough for Hodgins to fit down comfortably in a sitting position.
The Movie in the Making - S11-E18
Factual error: Angela try to recover some digital data (like SMS or the call list) from memory chip of a 2006 mobile phone. But there's not any memory chip on Angela's work table; there's a SO-DIMM RAM wafer, probably an old DDR which makes no sense: 1. RAM is a volatile memory, so after power off, data goes bye. 2. Lot of chips for a simple mobile phone memory 3. It's a RAM wafer. (00:28:50)
The Movie in the Making - S11-E18
Continuity mistake: The amount of squirt cheese on Aubrey's pop tart changes between shots. (00:32:40)
The Movie in the Making - S11-E18
Character mistake: Near the start Bones calls Dr. Vasiri, Dr. Resedi. This is a mistake as she has worked with Dr. Vasiri for a number of years and never calls him Dr. Resedi.
The Head in the Abutment - S11-E19
Character mistake: Hodgins flies a decapitated human head via drone all the way from the crime scene to the Jeffersonian. A distance of several miles over city and urban landscapes. This would comprise all the evidence and be a massive risk to public health. Dr. Hodgins would know how much it would mess up the evidence since his area of expertise is particulates, and insects, both of which would be compromised. (00:28:30)
The Head in the Abutment - S11-E19
Continuity mistake: After Hodgins asks for a drone we see Booth and Bones driving over a bridge. Camera cuts to inside the car and they are now in the middle of a town.
The Final Chapter: The Flaw in the Saw - S12-E6
Revealing mistake: At the very end we see Bones and Booth on the rolling log. In the front view the log is obscured from shot however it's clear from the motions of Booth and particularly Bones that they are stood on level ground, mimicking the actions of being on the log. (00:41:00)
The Final Chapter: The Flaw in the Saw - S12-E6
Continuity mistake: At the start the intern puts the liver to one side, which promptly disappears.
The Final Chapter: The Scare in the Score - S12-E7
Audio problem: When Max is telling Bones about the pacemaker, in a few of the over the shoulder shots Max is still talking but there is no audio. (00:03:00)
The Final Chapter: The Scare in the Score - S12-E7
Other mistake: It is found that the bad guys used Brennan's father's pacemaker to find where the safe house is at. An FBI agent at the scene then states that they "never expected Brennan's father" to be there despite him being the reason they found the place.
The Final Chapter: The Grief and the Girl - S12-E8
Visible crew/equipment: When we see the aerial shot of the harbour in Canada, the filming helicopter's shadow can be seen on the sea surface. (00:13:00)
The Final Chapter: The Steal in the Wheels - S12-E9
Other mistake: When Rolfe walks up to the platform with Angela at the start, he is 3 or 4 steps in front of Angela who swipes her card to grant access to the platform but no alarm sounds. (00:08:00)
The Final Chapter: The Steal in the Wheels - S12-E9
Visible crew/equipment: After Fuentes explains to Saroyan why he's not wearing the new lab coat, Fuentes tells Saroyan that he'll be coming to her wedding because they're family, and as the camera pulls back we can see a T-mark on the floor at his feet. (00:18:20)
The Final Chapter: The Steal in the Wheels - S12-E9
Revealing mistake: When Booth launches his car off the other car in the derby, the sparks that appear don't line up with where Booth hits the car. (00:35:35)
The Final Chapter: The Day in the Life - S12-E11
Revealing mistake: Aubrey takes a tablet of some kind. However if you watch closely you will see he drops it in his mug instead of in his mouth.
The Final Chapter: The Day in the Life - S12-E11
Continuity mistake: In Brennan's segment of the episode, the cake on Angela's fork disappears after Brennan points out that saying Booth's aura is "as clean as it's ever been" was sarcasm.
Answer: Answering my own question here but, having contacted various people involved in the production of Bones including Kathy Reichs, Hart Hanson, Eric Milligan, and Deirdre Lovegood who portrayed Taffet onscreen I finally have the answer. No-one know how she did it due to her constantly working alone. And she never revealed this information before her death.
