Take Down Nightstar Bugged

[Adeon Hawkwood]

So the mission "Take Down Nightstar" from Maria Jenkins seems to be bugged. I tried it on two different characters and despite scouring the map I was unable to locate Nightstar with either character. I think her spawn point might be bugged.

Did you clear all the roofs?

She is always on the roof, look harder

Did you clear all the roofs?

Yep, I know she normally spawns on a roof so I made sure to double check all of them as well.
