Night of the Sentinels: Part 2 - S1-E2
Continuity mistake: After Cyclops tells Gambit to blow up the fence and Rogue flies into frame, her headband and the patches on her uniform that are all normally black are now red. Additionally, the black encircled X on a red background on the left side of her chest is now a yellow X on a red background. (00:06:35)
