Alright so I was playing the Creature stage of Spore on hard difficulty and I was trying to get the knight archetype for space stage. To do this, I needed to be aggressive in Creature stage. It was really aggravating because everything just went wrong. The one time something went right was when I made a species that was giving me trouble extinct. However, for whatever reason, they were still there even after I killed the required amount. No floating into the air and disappearing, nothing, just them continuing to attack me. Of course, I was expecting them to be gone, so I was killed and the game immediately crashed. So, has something like this ever happen to you, a species becoming extinct, but not leaving like they're supposed to?
