Seeing weird spawn behavior with this mod. I installed this mod, then did a destroywilddinos. After a few hours, according to my S+ Tek Transmitter's dino scan function, I'm seeing Female Argentavis, Grffins, Rock Drakes, Snow Owls, and Velanosaurs, but no Basilisks or Gachas. Also not seeing Nameless (but I don't really miss them). Also weirdly, the Nameless aren't listed in grey at the bottom of my transmitter with the other relatively rare dinos that can spawn by haven't on my map (like Tek Quetzals and Liopleurodon), while the Basilisk and Gachas are properly listed there:
