I mean, no, even if you ignore the Canon-based plot-holes, the game itself has a lot of inconsitency by itself too, some based over NTR logic that if it was a shorter piece most would ignore (Like constantly emphasizing how Inoda has no real stamina or strenght IRL...except for sex when he has infinite of both compared to Kirito having both, and then doing the same in the game world...even though Kirito is super OP there and as such should also have infinite sexual stamina if only for his stats XD).
Yui's is just the most blatant one because it wasn't even needed, it was just Fujino 'clarifying' it for people who whined about it (Because there was no need as far as being worried by Patreon rules, Patreon doesn't give a shit as long as you don't show a 'loli' having sex, and not only was Yui specifically remade with a 'sexy big-titted Onee-san' avatar here and she herself established in-game that she "was made as an adult"...and technically Fujino is STILL violating Patreon's rules just for Kirito and Suguha's plot but there has been 0 issues there either as as long as you don't get reported is hilarious how much one can 'violate' Pateron's rules). Even if we ignore SAO's actual plot and say that Kayab was 40 or 50 in the Fujinoverse, it would STILL make no sense because there is no way he could have made Yui over 20 years ago because there was literally no technology available to do so in the early 2000s, and that is again ignoring that Yui by itself wouldn't even EXIST without the technology that made SAO itself, even in-game here in the Fujinoverse it was re-stated by the characters she was made to be an SAO AI after all so is not even a "contradicting canon SAO" stuff, just a self-inflicted plot-hole that woudn't have happened if Fujino hadn't bothered saying it, which ironically has happened a lot XP (Like how he felt the need to make that council member Silica's dad for no other reason than to justify why she wasn't appearing in the game despite nobody really thinking about her or wondering where she was, and so created the plot-hole of why Kirito never bothered contacting or checking out with one of his few friends from the death game again after clearing it) The SAO-related ones are just the most blatant, but even if the game wasn't SAO-based and you ignored all of it you can still find a lot of them, most caused by dragging it out so much.
Mind you, I still think this game is an amazing piece as far as H-games go, as stated before, and I admire Fujino's dedication to it and the amount of effort he has put, but that doesn't make its main plot any less of a giant plot-hole-ridden mess, I just don't particularly mind because I have had 0 investment in the main plot for ages, it brings some decent hentai of characters I like, and I got to see some very interesting and unique plot-twists you usually never see in these games XD
