Drifter body despawn and walking through walls

[Sparkle Kitti]

So I'm not sure if this is a bug or intended but, I noticed that when I killed a few drifters, a few minutes later they vanished. Also, I've yet to find anything from their bodies. I've probably killed 50 so far. A streamer I watch has started p[laying and it seems he killed well over 100 and still no gear. Again, maybe that's how it's meant to be, idk.

One other thing I've seen is a drifter literally coming out of the wall in my base. If this is not a bug, I'd suggest them leaving a hole where they came in from.

They do vanish rather quickly, yes. The chance for a temporal gear 1/75. Coming out of walls is not intentional and sounds really creepy
