Christmas Special 2012 - S3-E9
Continuity mistake: In this episode, Cora tells Mr. Gregson that she started reading "The Sketch" when Edith began to write for him. In Season one, episode one, Carson tells William to iron "The Sketch", because "her ladyship only ever reads the Sketch."

Continuity mistake: When Robert is in Debra and Ray's kitchen, as they talk Debra holds a plate with a slice of meatloaf on it. When she finally places the plate on the table, the piece of meatloaf Ray eats is different.

Continuity mistake: From the outside of the house, you can see the staircase and door are to the far left of the house. But from inside the house, you have a fireplace and the staircase to the right of the door. So you know it's not the same house they use in the show.

Enemy Fire - S3-E2
Continuity mistake: In episode 2-4 "The Funk Hole " which takes place in the fall of 1940, Andrew states to Sam that his mother died when he was eight years old. In this episode (Feb to June 1941), Foyle is looking at his wife's grave; it shows his mother died in 1932, which would have meant Andrew was born in 1924, and only 16 in 1940, far too young to be a Spitfire pilot. Also, his commanding officer states "the younger pilots look up to you, Andrew", before one of the "younger" pilots (age 19) is badly burned in a crash in Andrew's plane.

Continuity mistake: When Mr Bean realises that the Burglars are behind him, the small burglar's left gold earring disappears. After they tie up Mr Bean, it reappears.

Continuity mistake: Cory is trying to get a date with Cindy when in the episode before they already became boyfriend and girlfriend.
Suggested correction: This series is not meant to be taken in exact chronological order. Most episodes have no dates or time of the year set. Unless we have reference to a date or time period of the year; we have no way of knowing if the continuity is truly off as this series is meant for the episodes to be taken within a generalized time. Not in any specific chronology except for a few where the time period is specific. Neither this episode or the one before it has reference to a date in time.
Suggested correction: While the other correction is wrong, the real reason this isn't a mistake is because the episodes were aired out of order they were produced, which means it's not a mistake within the context of the show. "Bend It Like Baxter" (production code 315) was filmed before the previous episode, "Double Vision" (production code 318).

The Night Dr. Loveless Died - S3-E4

Continuity mistake: When Sherlock is backstage at the circus and finds the yellow spray paint, he draws a line on the mirror. In the next shot, the line he drew is completely different (and in fact is more of a squiggle). (01:07:40)

Continuity mistake: When Mr. Roper tries to explain to the girls and his wife what he was doing in Jack's bedroom, watch over Mr. Roper's left shoulder on the shelf.
