Elite: Dangerous PvE - Mobius

So there I was running a navy progression mission to Dalton Gateway. First the background music stopped abruptly, then I noticed the SC lines juddering and joystick input was starting to get sluggish. It's then that I noticed the Radar or Dradis as I like to call it .

Seems to have been some sort of AI storm, there were so many contacts it looked more like a RES or a HI CZ than a supercruise through the system. It got to the point where joystick input happened about 2 seconds after I actually moved the stick, the lag got that bad.

I've never seen anything like it before.

were there any CMDRs present? were any of the contacts white? i'm just wondering if someone dropped a huge bundle of cargo and that's what caused the lag

There were 2 or 3 other hollows, don't recall many whites apart from FSD wakes, would dropped canisters show as white in SC? There were a huge number of solid AI squares though, will post the screen cap when I get home.
