Missing Items After Death

Died in Nether due to pigmen bug where once you hit them, they will NOT stop agro on you no matter what you do. I died and not even 2 minutes later, I return to where my stuff was and it was gone. I'm 100% sure I'm at the area that I died. I really hope this pigmen bug gets fixed because I cannot do anything in nether without being attacked and I have lost so many good items due to it.
