In NG+ when you roam the city, you frequently have a legendary renegade encounter that yields high level gear.
I assume that when the player gets too far away from the renegades, they disappear because the game assumed we didn't want to engage them.
The problematic part is that I mostly travel via paraglider which has a huge vertical mobility when I take off using the air ventilators.
This often makes the encounter disappear, even if I wanted to fly towards them.
I understand that I created a large distance by using the paraglider that likely resulted in the encounter's disappearance but maybe this wasn't intentional by the development team.
If we could have a more lenient vertical distance to them or just rely on horizontal distance it would keep the encounter even if players fly around.
