My favorite story of corpse loss was very early on, Chin-To lent me a white matte robe while I went to try get my own. I was in the middle of nowhere playing in Israel when you were all sleeping.
I fell into a hole that was oddly shaped and died, this is when there were warnings about climbing on mountains, but in my case it was just a hole in the floor.
So I spawned, ran back, and my corpse was stuck in a strange loop where it would slowly fall down the hole, then pop back at the top, when it popped back at the top I could click it and view the items for one second, not even fast enough to get the icons. Note I was low level so my corpse didn't last that long.
So I sat there trying to VERY QUICKLY click the corpse, press the action button (e?) click the left most item, click the pickup hotkey, and slowly but surely I retrieved my items. I managed to get the robe, and then a few seconds later the corse dissapeared and all the items left (2-3 of them) fell to the bottom of the hole and I couldn't get them.
I think I might have had more than one corpse in my attempts to get the first one, I don't remember exactly, I just remember being so frustrated, but the feeling of success I got when I got the robe back, it was
That's my story.
