Do you take fall damage? And do you see blood spatter when they hit you? There’s an invulnerability switch for testing that disables both but it’s supposed to only be accessible in debug builds.
there is a quick bloodsplatter where they hit me (was so quick , i mistook it for their muzzle flash) as I stand quite close , dont hurt me; nothing when I shoot them . as for fall damage; I walked off a highplace and it did kill me; not so much as fall damage as in instant death.
