Nightmare missions on Earth have a higher drop chance for Kubrow Dens to spawn unless it's a Defense/Interception or night, which cycles every 4 hours (Not the same as Cetus timer). Cervantes on Earth usually has 4 to 5 Kubrow Dens but the drop chance is very low, so you will have to repeat the mission a couple times if you are not lucky.
