My friend killed me and I left the game right before i died and when i returned none of my stuff was there it was like 1 minute until i had returned my stuff shouldn't have despawned in that timeframe

I have come across it too... Yes this does exist... You actually did die but after you logged out... Meaning your stuff is gone forever...

Thank you for your report!
