The only two "not canon anymore" things I can think of are the Ishgardian vigils, which are completely different, and possibly the 1.0 meeting with Ifrit. In ARR, you meet Ifrit in exactly the same way, but he acts like he doesn't have deja vu about it at all. He acts like he's never met "the godless blessed" before, and in the end actually comes to the exact opposite conclusion as he did before. In 1.0, he says the Paragons said not to harm you and he'll let you go if you agree never to summon another, and in ARR he says the Paragon said your kind can not be suffered to live. In the meantime I've just attributed it to Ifrit forgetting the Warriors of Light like everybody else did and somehow he forgot the whole of the exchange along with them, lol.

Nope. Unless...(more on that below).

The cave itself was referred to as the Crypt of Xandes I in 1.0, and then Erik said that Xandes was entombed in a tower of Crystal, and then Xandes shows up in Crystal Tower, so I think that was the implication, yes.
BUUUUUT

Bingo! Even in the 1.0 transcripts, the English, German, French, and Japanese dialogue didn't agree on where the "tower of crystal" Erik was talking about was. My theory was that Square Enix decided to move it between versions so that CT wasn't right next to Castrum Centri (then Castrum Novum) anymore, and then two languages referred to it's 1.0 location, two referred to its planned 2.0 location. So that's a huge retcon, right? Kind of... Think about it this way...
FINAL COIL SPOILERS
A good chunk of the realm was destroyed by Dalamud's fall, and was then reborn due to the interference of the newborn primal Phoenix, whose power rivaled Bahamut enough that he was able to tear him apart in midair. Phoenix attempted to sacrifice himself and return all that aether to the planet, but the process was warped when Bahamut consumed what was left of Louisoix's essence, including bits of the Phoenix transition.
Because of that, Square Enix can write off pretty much any map discrepancy as the "imperfect" rebirth of the realm. They can say it's why Gwyr Aen and the Fury's Gaze are both near Ishgard now. They can say it's why the Gelmorran Ruins came so far south. They can say it's... why Crystal Tower isn't where it should be... if they wanted to. But I can't answer for sure.
Still, it's an interesting place to re-use such a small resource. They even to it in a that was way more complicated than the small, simple part they reused, which makes me think perhaps there's a chance that they used that particular shape because there's some connection to the old Crypt of Xandes... though, beats me what that might be...
