I was playing on my survival world I created to complete the game, I had beaten the ender dragon and was killing some wither skeletons for their heads to spawn and defeat the wither.

I changed the mode to hard in hopes of increasing the spawn rate of the wither skeletons, I had full enchanted netherite tools and armour. I was killed by the withers, came back through the portal and half of my stuff was still there, but the others were gone.

I was very disappointed and upset to see that my enchanted netherite gear that I had spent over 2 weeks on getting had disappeared.
