It sucks to be spoiled like that.
At least it was a meme, but would have preferred not have seen that either since the image itself was really spoiler-y and takes away the fun of the actual chapter.
I had to go back and see what @Keimichi was talking about because I skip the discord section, but yeah, I think it's better to use scenes from the current or previous chapter rather than the next one to do those jokes.
@Sheeplet It's not really the translator's fault; I think those are originally chapter "previews" directly the raws. The translator was considerate and made them into memes instead. Which is fine for most chapters, since not having the text removes the context so it doesn't actually spoil much. It's just that for this particular one, image alone is enough to spoil.
