yes there's a few random things going on,
I was at a springbok spawn a bit west of Bakti and there are random springbok grunts and gallops coming out of two huge trees with no springbok in sight.
I've been near springbok very close to Bakti and the sounds seem fairly in sync by comparison.
The other odd thing is no matter where you are it seems the same ambient bird noises have no direction/location, you can be near lava, on the plains or near trees and you hear the same bird noises as if they're close by, they only seem to change for day and night.
Not a huge deal but maybe it's also easy to improve ?
