Sousou no Frieren: Fern criticised for becoming 'fat'

As previously reported, the popular manga "Sousou no Frieren (Frieren: Beyond Journey's End)" has entered an indefinite suspension. This is normal for those who have followed the work since its inception, but it may have taken those who came to the manga by surprise after the successful anime adaptation recently aired.
However, because they don't have much to do while the play is on hiatus, fans debate about the more particular things about the play, and something that caught the eye was an illustration of Fern where she is really noticed with a very different design than usual.
In the illustration, which is definitely not recent, we can see Fern combing Frieren's hair and making two braids on him, which she also wears. However, it seems that this hairstyle change confused Tsukasa Abe, the manga's illustrator, a bit, as Fern's face design was more "chubby".
It didn't take long for this to be noticed by fans, who debated whether Fern had become fat over the years within the manga:

And of course, the comments were not long in coming:
- "The author is going too far to provoke netizens."
- "A fat girl with questionable morals and who is always angry and trying to manipulate others, that's Fern."
- "It can't be helped, the only people Fern has ever interacted with in her life were a drunken priest and a selfless elf."
- "It seems that Fern's special spell is to become fat."
- "Fern gets uglier with each passing chapter, I'm glad Stark doesn't interest her much."
- "The personification of fujoshi, without a doubt."
- "Don't you think the main problem is that the nose is drawn in a horrible way?"
- "She acts like a mother and now she has the body of one."
- "Another indefinite hiatus, they should get him out of weekly serialization once and for all. Certainly the authors are not ready for such a job."
- "There's definitely a big difference between the manga artist and the anime artist."
- "Does Fern now have diabetes? I hope there's a spell for that!"
- "This is simply because the artist is bad. Fern is officially a slim, attractive girl."
- "Fern is the one who eats huge portions of food and stays hungry."
- "Even if she's fat, she's not one to be powerful but to be fast."
- "It looks like they're going to have to go after the magic of staying thin no matter how much you eat."
- "It loses weight as they walk and gains it back when they arrive in a city, which is convincing for a medieval story."
