Long story short I have to capture some Simaris targets (with extra steps) for a riven challenge but they refuse to spawn no matter how many missions I play.
First I tried with commandos - played over 20 grineer missions all over the system and not a single time did one of them spawn as Simaris target.
Then I cancelled the hunt and got a new one with ancient healers - again, played over 30(!) infestation missions all around the system with different modes and not a single one spawned.This cant be my bad luck, are any of you guys experiencing similar things?
I didn't find the right solution from the Internet.
