i was in the nether looking for a fortress, then my game froze. It was frozen for a couple of minutes then an error message occurred, following the error message it said “you died” and i still saw my items floating there. Then when i respawned back in to retrieve my items, only a couple items were there, and my netherite sword and pickaxe were gone. I dont think it de spawned since it wasn't 5 minutes yet.
