When I killed some Legionaries, assassins appeared instantly and kept hunting me. Since I met Caesar for platinum chip, assassins were disappeard. But I didn't complete caesar's quests. After I killed him, I and Boone wiped whole legion areas including the Fort. Now I'm killing and killing a lot of legionaries but no assassins come after me. I know where they appear so I traveled nearly all around the map waiting for them. They just disappeared, Where they've gone? My reputation is 'vilified'. How can I meet them? Is this bug? I miss them, I enjoy make them fight with NCR or Merchants each other, then killing them was my fun.
