Bug players became ghostly

[HolyCookie]

don't really know why or how, but the players became a bit vague mostly their leggs disapear, sometimes their whole body. but at the border of normal and disapeared the body is vaguely visible as a seethrough exectly like a ghost.

never seen it before. showed up for me after shipyard update. might have something to do with back ground or lighting so ill tell that too. white advanced armor and white light.
