Also how famine, bombardment and natural disasters can't wipe out a planet's population, you can't sterilize pops but keep them alive (short of slavery with reproductive rights disabled) yet somehow you are able to exterminate a pop even if that would cause the planet to become uninhabited (surely the last pop would take issue with self-extermination?). And it really, really is unfortunate that the cloning tanks do not let you clone pops :<
Hold on, since when does famine and bombardment not kill pops? I lost a colony once, it was being bombarded enough that the pops couldn't grow food. One day, every pop on the planet just...vanished. The enemy didn't capture it, it simply reverted to being an uninhabited world.
Also the famine modifier stuck around until I eventually recolonized. Was worried that the new pops would just instantly die >_>
