Lately a lot of wildlife, mostly all are predators (occasionally amaradons) and mammoth birds are invisible. They only appear or spawn? when you’re standing right in there face.
It’s super scary because you could be minding your own business when sudden a Blitzer materializes out of thin air and pounces you, or a group of mammoth birds swarming you.
Sloths, Elite nomads, Dune beetles and Armadons are also effected by this, stryders too but they aren’t bothersome.
