They freeze; has anyone else seen this?

I've been having packet loss problems with Comcast lately, and Destiny seems to be my canary-in-the-coal mine for these issues. Whenever I'm having large packet loss, the enemies all tend to stand around and/or pop around. Generally this only lasts for a few minutes before it disconnects me, though.

head shots blow up enemies, if an enemy blows up next to a shank, perhaps, it kills the shank but doesn't trigger it's body removal. The Shank doesn't blow up, it just stops.

Saw a dead one floating in the air tonight while doing a strike

But nobody home

But nobody home

Of course! I kept trying to punch & shoot it while running around. It's never a cool thing to get killed by a shank so I wanted to make sure it was perma-dead

That's definitely it. My scout rifle has the Firefly perk, and any Shanks that get killed by the explosion simply fall to the ground. They don't blow up or anything. Just an intact, immobile Shank.
