There are a ton of continuity errors in this film anyway, and most probably wouldn’t be noticed except on repeat viewings. One of the ones that’s always stuck out to me was Rey having the lightsaber activated in the drone shot during the training montage, even though the shots before and after have it deactivated. But I doubt anything can be done about it, so…oh well.
Yeah, I noticed there’s a ton of moments where the lightsabers are just suddenly on / off. Like, no activation / deactivation sequence or anything like that. It’s one part that really underscores how much the movie’s pacing was accelerated in editing. But like you said, not much can be done about it.
