Or we can assume they destroyed it for good, or sent it to Abeir (alongside the lake), etc... Given time, I can even came up with a fix that I actually like. The point is, however, that I'm aware of the reason why they didn't include it in the map (most likely because, as you say, there was scarcely anything about the city and they either didn't knew it existed or actively decided to remove it). And that for me, is what doesn't allow me to enjoy this: I'm pretty aware of the truth. At least, not for now. Perhaps, over time I can get over this.
Enlil is a jobber. He was so weak by the end of the novels, I don't think he had the power to pull that one. Nanna-Sin was not even a god by the end of the novels, just an immortal dragon turtle. And Selûne... may be she do has the power for this, but she never cared for the dragonborn. She just saved them by accident and left them to their own devices as soon as she did what she had to do in the area.
Again, knowing the lore is what makes me unable to enjoy the easy fixes people is coming up with, because I have an idea of the Doylist explanation for things. I need time to process this, and came over with fixes I like and consider logical and lore compliant.
Enlil managed to block the Sundering from teleporting two big Dragonborn cities to Abier. That is not nothing given that he had no time to build his power back up to were it was in ancient times. He's had at least decade to rebuild his worship in places like Chessenta, Messemprar, Dragonborn city states, etc..., restoring a measure of his power plus. Asmodeus protects the Dragonborn cities because his pissed Gilgeam makes deals with Grazzt, the civil war in Tymanther/Unther has become an extension of the Blood War.
And Selune is no slouch either
