I was playing minecraft on 1.18.32 (latest 1.18 update) and I got disconnected from the multiplayer world because update to 1.19.
I quit world, close game, update to 1.19 and relog in to the world and some items were completely deleted. The last few actions I did which involved any moving of items was deleted. My sand and coal were deleted which I moved from my inventory to a furnace and my diamond shovel was deleted which I put into a shulker box.
