Updated most of the volume a couple weeks ago, but dragged my feet getting the last couple ready for no good reason. Anyway, volume 3 should be fully updated now. The note page for 33 has the details.
There is one thing I did not do.
In the volume, it's clear that once Mimiel comes back as an angel in chapter 33, all of her lines are actually “highlighted” with a screentone. This does appear to be present in the digital serialized version as well, but I did not notice it since the washed out tones and low quality just made it appear as artifacting (which you mainly see around lines in the first place).
To make things worse, I usually run pages through waifu2x to lessen said artifacting, and as a result, you can barely see it in the actual chapter as it was released.
You can see what this is supposed to look like in the newly added spread (page 40), but it just didn't feel worth it to try and redo the affected pages to try and make this more visible.
(you should buy the volume so you can see the art as intended imo)
Anyway, that's all.
