Other mistake: When Seiya blasts with his special move the helicopter, causes an explosion, but there's no damage on the vehicle nor smoke, fire or any sign of what he has done when we see it spin and eventually crash-land. (00:13:50)
Continuity mistake: Shiryu puts the medal on Seiya's chest (no idea where he found the string to craft a necklace with that). Pegasus coughs and the medal shifts a little, but not by much. The three remaining knights talk and vow to get the armor back while they leave the moribund lying there. He does not move during that, and yet when they take off the dog tag moved more to the left. (00:16:55)
Other mistake: When Shaun KOs the first Black Knight with her chain, the other two Bronze knights are at distance from the enemies. However, they are quite literally at their feet a moment after - and they got there by crawling, even. (00:20:00)
