The title pretty much explains it as best as I can. It's happened three times. I believe I was still on Vulcan for all of them. As soon as the mob died, it did a bunch of spinny stretchy flip-arounds and then landed on the ground super stretched out.

Has this happened to anyone else? I have a saved game when I'm standing in front of one if the mods want to look at it.

yep, there were a few mobs that did this. noticed they addressed it in the latest patch notes

Pretty par for the course. It's (fun) Early Access stuff.

Yup happens every so often in multiplayer; I haven't hit it (yet) in solo play.
