Star Trek: The Animated Series - Images for S1E11 and S1E12 swapped
Season 1, Episode 11 - The Terratin Incident shows an image of the trapped ships from Season 1, Episode 12 - The Time Trap. Conversely, The Time Trap shows the image of the miniaturized crew from The Terratin Incident.
Edit: I said Season 2, Episode 12. Corrected it to Season 1, Episode 12.
