Eve can be standing in brush doing nothing and an enemy that enters her vision radius will see her.
Since Eve pays so much for her stealth (to the point where she doesn't have anything else) it would be nice if that stealth could, you know... function.
Did they have wards inside the brush? If so, upon entering your vision radius they would have spotted you because thanks to the wards they have vision inside the bush.
they won't see her but if she leaves the brush they will; it is just letting you know that her stealth is no longer functioning to protect her and you are relying solely on the brush
They cannot see Eve in a bush unless the bush is warded. Note that it doesn't have to be a pink ward - If an enemy is inside of her stealth radius and has vision of her location, they can see her, even if they can't directly see her with their own vision.
This is intended behaviour.
