[Bug] Invisible scavs on patch 0.16

One issue I don't see anyone else talking about this patch is invisible scavs. Went to play duo with my buddy and on the first run on GZ we he encountered scavs. The issue is, I was standing right next to him, watching him unload his mag into an empty doorway and later looting them. It was such a confusing experience for the both of us.

Initially I thought this might be a one off, but just encountered it a second time, got killed by a scav that was apparantely right in front of me. No sound, no visuals, just insta death.

Has anyone else encountered the issue?
Patch is beyond broken and borderline unplayable.
