Classroom of the Elite received heavy censorship, to which they apologized, though I forget if that was the manga or the novel.
Mushoku Tensei: Jobless Reincarnation had whole storylines removed because of a forced sexual scene which ended up being an important plot point that followed through multiple volumes (ergo why they had to re-translate and re-release multiple volumes)
I Think I Turned My Childhood Friend Into A Girl had an intentional English mistranslation to which the company also apologized.
For that last one, you can imagine how modern day partisan politics here in the west colored the translation, which also because it alters the core concept intended by the author, created complications and polarized opinions. To be more overt about it, from my understanding, it's some sort of BL story about a femboy crossdresser, but instead they turned the male romance interest into a trans which alters a lot of the context and is more of the whole femboy erasure issue that's popped up every now and again, similar to the whole tomboy erasure problem.
And if I recall right. Seven Seas also promises to never censor their mangas. But they got caught repeatedly censoring their mangas.
Basically. Seven Seas is a group who unfortunately have bought up the licenses for a bunch of stories, butcher them and only apologizes once they get caught red handed and knowing how poorly paid people are for localization/translation jobs, it's unsurprising that official translations can end up being botched up. Like how for example the fan community of Overlord swears by the English translation of the Chinese to English fan translation while shaming the official JP to English translation, despite how the fan translation has a literal chinese telephone issue of translating JP to Chinese to English, but ends up being seen as the better translation in the end.
I believe there was one other Light Novel for which they got caught red handed, but I forget what the title was. I'm sure I could probably find it if I did some searching around for an old article.
