Ender-Pearl item loss bug.

I threw an ender-pearl into the air, and it landed, I was low health at the time and died, I live in the same village this took place in, and it took me less than a minute to get there, the items couldn't possibly disappear, but they did. I returned to see no armor, no XP, keep in mind, a raid was happening at the time, but no pillagers were spawning! I find this really weird.
