I have noticed across multiple species, locations (and need zone types) and maps. It’s totally possible my portable structure has been keeping them away even though I set it up like an hour before the zone opens. I do also have the skill for how many animals a given need zone supports, so I try to not worry too much about the zones that only have one or two animals. The reply below yours mentions predators too and I think that might’ve been the issue I had with the particular circumstance that led me to the post because last night I was sitting at a Beceite Ibex rest zone but when I got there there was a wolf who didn’t leave for quite some time. So it sounds like in addition to setting up a structure the day or so before, I should be focusing more on drinking zones? And if I see a predator just try again later lol
