Does anyone know how to curtail the generating of Aliens? I've found at least 20 already wandering the worlds and I'm sure there are more I haven't identified. I don't mind a few but this is getting ridiculous. I've tried MCCC but it only controls Alien births, not spontaneous generation of Aliens by the system. I would be fine with the usual half dozen or so living on Sixam and maybe 10 more wandering NPCs, but it seems like I'm seeing more Aliens than humanoid Sims when I'm out and about. The main reason I know so many are around is because they aren't even disguised. I've written their names down so I can delete most of them from the Households panel, but before I do that, I'm hoping I can find a way to limit their numbers so they aren't simply replaced by more Aliens.
