Sometimes corpses glitch and then start flying around
Hey there, I just had the same happening today, but it was the leeches from those exploding guys doing this, exactly the same thing, textures got stretched like in the video and they were popping around.
This was both unsettling and quite amusing. Didn’t seem to be game breaking, though… although I didn’t stay logged in long enough to watch what was going to keep happening.
Replication successful. Other mobs spawned right after wolves were killed, which didn’t happen yesterday. Could be because I did so in a different part of the Keep?
I didn’t get a chance to capture it in an SS or a video, but the wolfspasms happen with more than the quest, apparently. I killed two wolves just now, while I am exploring Nameless Pass, and both of them started flopping all over until they fell off the edge of the mountain. 
After defeating some enemies, returning to an area can sometimes cause ragdolls/corpses to flop around uncontrollably. See video for example.
Running the game on a 1080ti gpu, i7 8700k cpu. Unsure if that matters.
Have had similar ragdoll issues in previous builds.
This happens in my game aswell, mostly with wildlife.
Same with me and also was with wolfes.
I’ve noticed this if you do lots of crucible attempts, the defeated enemies from previous attempts stay on the ground and sometimes bounce around a bit of their own accord.
Still happens with Torn Leech exploding monster as of Hotfix 6. Specially if it can’t dies before producing leeches.
Below is the GIF showing how to do this.
Would you be up for trying to clip that Silver? If not, I can do it to!
