The Wedding of River Song - S6-E14
Other mistake: When the Doctor walks into the control room at the base, the time on the computer is frozen between 5:02:57pm and 5:02:58pm. The Doctor grabs River's hand, and time begins moving up to 5:03:00pm before he is restrained. Later, when the Doctor and River kiss and time begins moving again, the time is 5:02:00pm.
Other mistake: When the Doctor gets George's psychic cry for help, he's shown reading the message without opening the wallet containing the psychic paper. This despite the fact that all previous instances of the Doctor receiving psychic messages this way has required him to open the wallet, suggesting that the wallet itself does not display the message. (00:02:02)
The Impossible Astronaut - S6-E2
Other mistake: After River shoots at the astronaut going into the lake, she drops her arm. The next second, she turns around and the gun is holstered without her having made any movement to do so, and there was no sound made.
Suggested correction: The holster is low enough for the subtle movement her right arm makes to be using it. As for the sound, the removal of her gun doesn't make a sound either. The only sound heard is directly before it when she put her medical scanner away.
