The NTSC version of the GOUT is missing one frame at that spot (which is a reel change) compared to the PAL version. Since the audio is synched to the NTSC, there will will be a corresponding loss of synch in the Despecialized Edition at that point, with the audio being one frame ahead of the video.

We really need to be more vigilant about this kind of thing so there aren't any synch errors in the future.

From the beginning to that spot, the audio is about 21 ms late (compared to Team Blu's GOUT upscale), and so from that spot to the end, it's 42 minus 21 ms early, so there's basically a 21 ms delay (late or early) in the whole movie, which is not that noticeable.
