@the_kettle Great, thx for helping confirm.

I know the title sounds implausible, but I had one Delta 03 crash while fighting one of the large drones in the open world. Didn't think much of it, had zero issues until I got to the rooftop fight with a marauder drone on the Pentagon mission. As I was fighting it, it was delta 03 disconnects constantly. After defeating it (thankfully my progress on the fight was remembered after each disconnect) connectivity cleared up entirely. It's either one heck of a coincidence or there's something odd triggering with the drone.

EDIT: The rooftop fight was a few hours later, so that should rule out a short stint of spotty ISP service.
