That happen for me two. I Fell form a high place and I spawn not that far away form where I died. When I got there there was nothing on the ground as if I never died. No five minute de-spawn time. After a day or two I spent a few hours getting my things back but then my Minecraft shutdown on it's own. When I got back in I was not standing where I last where I was standing where spawn was ( On top of my house because we build our house on spawn) then I released my inventory was empty as if I never logged on into Minecraft to re-make my things. I also released that my ender chest was empty ( It had all my valuables) and that my armor and experience was gone.
