Went into the Nether to trade with a piglin, trapped one a few blocks away from my nether portal in soulsand and began trading, after a little while i went into a shulker box to get more gold, and the piglin i was trading with became hostile and killed me, after which i came back via my nether portal and my items were already despawned. I returned immediately though the portal since it was beside my house. The chunk was unloaded since i was in the overworld and there was no exp on the ground, none of the items were in the floor or roof from what i could tell, also no netherite items survived and there was no lava or fire nearby
