FYI, next time you should also try and get in contact of the uploaders (@ma_ko in this case) or reach out directly to the scan group to see if they can fix it themselves. Just mentioning it in the comments does not guarantee that the right folks will see it.
Anyways ... @ma_ko, seems like the fixed page is on the scan group's website already, so I've gone ahead and downloaded that webp image and converted it to a png to edit into this chapter for now.
