lost items/ items disappearing

on death in my survival minecraft game (20w15a) ive lost items on death twice. the first time was in the end and i lost it all and the second time i was in the overworld and died in  midair, i lost half my items including my maxed netherite sword. im not happy about that , also no it couldnt have been destroyed i was over water, i know that for sure.. sorry for beeing so agressive im just still mad about it, its not your guyses fault :/ 🚿
