Sorry for my bad english.
Version: Forge 27.0.24 Minecraftversion: 1.14.3
While in the Nether i was fighting some blazes and died. Direct after this i couldn't revive me. I leaved the game and rejoined it. I revived at a point some steps before my death with all my stuff and found a copy of my stuff at the point of my death. That happend 2 times one time it happens on singleplayer and one time on multiplayer.
