Continuity mistake: "The Time of the Wolf": Robin slays his evil twin and leaves him on the grass near the standing stones. The body then changes positions without anyone touching it. When Robin leaves, its head is pointing to screen-right. But when Marion arrives, Evil Robin has done an about-face: his corpse is now pointing to the left. (01:21:00)
The Return of Optimus Prime (1) - S3-E29
Continuity mistake: At the end of the episode 'Dark Awakening', Optimus is seen without an eye and an arm, he also has other damaged points, but at the beginning of this episode, when Jessica and Gregory get to Optimus, he is in perfect condition with no damage.
Continuity mistake: The intro sequence shows Landon on a desert road walking toward the camera. There are no mountains or hills visible that are nearby. Suddenly when Victor French shows up there are mountains and hills.
Suggested correction: While it is true, during opening sequence, Jonathan is walking in desert. When the camera shifts to Mark, it is implied that much time has passed by the time Mark comes upon the pedestrian, Jonathan, who by this time is coming into hill country, soon to become mountain country.
