no please i love this, and i also like the idea of of it potentially being a problem that they kind of brought on themselves/was involved in somehow, some crazy act of hubris or whatever? when i first read your idea the first idea that came to mind was honestly something atlantis-ish, of an advanced island community perhaps that had a natural disaster or even something like - overworking the land and causing a collapse (the way we think of for like, land that's been over-mined that results in more earthquakes, etc). or some sort of political upheaval or civil war that left only a small group of survivors? which sorry i'm just thinking ideas and throwing things at you!
