After killing a Player his body disppear after thirty seconds.
So there is no time to loot his Body. This is really terrible because often you got more than one opponent. So nobody is running to an dead body if he knows there is another enemy out there.
In the last patchnotes i read a fixed issue:

• Systems: Disconnecting dead player would delete the body after 30 seconds

So as it seems this fix did not work !
