Other mistake: When Cade is fighting Savoy, Cade jams his thumb deep into Savoy's right eye socket. A moment later Savoy is seen with no right eye injury.
Other mistake: During the introduction of Attinger, he is holding cards of the Autobots explaining what happened to them. One such card is of Ironhide, listed as last seen in Chicago. Ironhide was killed in Washington DC at NEST headquarters by Sentinel Prime in Transformers: Dark of the Moon. He didn't even participate in the Chicago battle.
Continuity mistake: Optimus and the car Tessa is trapped in are caught in a net and are pulled up to Lockdown's ship. Cade then jumps and grabs onto the net whilst it is being raised. There is a brief moment where Optimus is not visible inside the from the net, before being visible again in the next shot. The CG artists likely forgot to add Optimus into the shot during post-production. (01:22:35)
Trivia: One of the KSI Transformer prototypes transforms into a Cadillac Cien, which is the same car Tom Lincoln drove in The Island, also directed by Michael Bay.
Chosen answer: It's not explained where he is. The most likely assumption is that he is probably married to Carly living somewhere. He is not in the movie because it is mainly the choice of the writers to not have him in the movie.
