I'm having the same problem. I'm on Mac in Desktop mode. When I shoot any part of any girl, her whole body disappears along with whatever piece I hit. I'm using the laser pointer and I'm almost positive I'm not hitting her body by accident, as the game continues as if she's still there. Her clothes float in mid air, she still makes sounds and reacts to other devices, and darts stick to where her body should be. However, her actual body is just invisible.
Also the dildo seems to be invisible.
