How many people died during the Neomuna Invasion?

I've been thinking about Lightfall and how I don't like the story. Not the actual story and characters because I didn't find them that bad ( even Nimbus,their dialogue feels cringe but they're two years on the job as what is basically a superhero so I get it and don't mind) but the world building surrounding Neomuna just feels so self contained and unexplored that I feel like it's feasibly possible it could never be mentioned again.

Part of that was the invasion itself. Correct me if I'm wrong, are the casualties of the invasions in the ones? I remember them explaining that the city evacuated to the Cloud Ark early on, placing them all deep and safely underground and only attacked by Nezerac before Root of Nightmares. Even then though, Nezerac only gets one guy to kill someone before we defeat him so that goes nowhere. So, going by that, I think we're meant to believe that the only casualties of the Shadow Legion Invasion is Rohan.

While that's a major unprecedented lose for Neomuna to lose Rohan, the fact that they made it out completely scot free feels really lame to me. The fact that the city basically was the frontlines for the end times only for the populace to exit scot free feels so self contained compared to other expansions. Previously, even when we win, the expansion story lines wouldn't just end. Rather, they'd leave some new details or other hints that foreshadow something new to explore later. Neomuna has none of those, by the end of the expansion, we know everything about Neomuna's history, their connection with Rasputin and Earth, where the Puuka come from and the population is super chill with us because we saved them all. But, all of this hinges on me being right with saying that the Shadow Legion killed an estimate 3 Neomunians. Am I right?
