Enemies disappear after being killed

Just over half of the enemies I kill disappear. No body, no weapons, just gone. I can see that they start the death animation, but then the assets just disappear. I’ve just started out on the first scavenge mission, so I’ll see if this continues beyond the opening missions.

Anyone else?

It’s seems that the debris of scenary destruction also disappear, which takes me a little bit out of it.
