Other mistake: When the family gets to the top of the mountain Brian goes left off-screen to pee. Lois says "we proved we aren't second best." Wideshot shows the Fishmans sitting there. They would've all seen them when they got there, yet they are shocked when Ross says "Well look who finally got here." And they are only inches apart.
Yug Ylimaf - S11-E4
Other mistake: Everything goes backwards in time and goes that far back that Meg (who is voiced by Mila Kunis) goes back to being voiced by Lacey Chabert (who voiced Meg in season 1). However, when Lacey Chabert does her line to Stewie being in the Griffin house for the first time, it goes back to Mila Kunis when Stewie is "reborn". However, if everything was going backwards and Brian fixed everything to make it goes forwards again, then it still should have been Lacey Chabert voicing Meg, not Mila Kunis. (00:16:30 - 00:19:35)
Lois Comes Out of Her Shell - S11-E6
Other mistake: When Lois goes to Justin Bieber's dressing room, when she enters the room and Justin looks at her reflection in the mirror you can see her arm disconnect from her body as she talks to him. (00:17:15)
Other mistake: Peter is in the hospital and Lois is there talking to him. There are 2 IV bags and a heart monitor next to his bed. The monitor shows his heart beating normally yet there aren't any wires hooked up to him.
Other mistake: When Peter was rescuing the Fishmans he totally missed grabbing the woman's hand but she didn't fall. (00:19:50)
