This is a much bigger issue. It happens on plain cut scenes, not just when dying. Next time you are doing dark beyond on the moon, watch your ammo count. When you pull out your ghost and scan the dead guardian and go to cut scene, when you come back I GUARANTEE YOU HAVE LOST AMMO. Did you die, NO. I have gone into the cut with 40 fusion rifle rounds and come out of cut with 23. What the frack did I do to deserve that? It happens with heavy as well.
