I believe I have had this same bug occur 5 times or so. I was indoors most times. I know there is a bug where gunshot sounds do not play, but that would not account for some of the deaths. I feel it has happened in areas where I could absolutely not be shot from any possible vantage point or window, and with backup that was between me and the door. After my death, teammates faced no threats for many minutes after and heard no gunshots.

Same thing happened to me.

Had this happen 10-20 times, easily. Seemed random.

The idea of starving to death with a backpack full of food cracks me up. Smashing the can on the ground or with a tool while losing up to half the food sounds sensible.
