As far as I experienced, the bug is that you can see your body and not that you cant loot it! To clearify, when I played with my mates it often happens that one of us said 'my body is still there but i cant loot it'. But in (i think) all cases it was only visible for the owner of the dead body. The rest of the group couldnt see it. So it probably disappeared after the 10 min or somebody hided it. --> It is correct that you cant loot it, but you shouldnt see it ;-)

In my opinion the rates are way to LOW! Once you are hydrated, energized and healthy it is easy to keep it up like that. I played about 300 hours, never died because of hunger or thirst even though i dont loot cities very much. more than 50% of food i dont even collect cause i have no space and need for that.
the ONLY point i agree is that we shouldnt respawn close to starving.
