At 1:37:40 in Return of the Jedi (despecialized) it appears that Leia fires off a blank from her blaster pistol yet no blast was ever animated nor sound effect added. Its easier to see if you watch the film itself but I’ve included a screenshot of the original and my own fan edited effect. I’m not sure if Ady is aware of this continuity error but I found it myself pretty recently.
