I was playing my Minecraft world with someone, this other person hosts the world, we were playing normally, this world had a few days and we got a home, places for animals, villages nearby... Just now, we went on a trip far from home to explore and find new things, and when we were back, all our tamed animals were gone, all the nametagged animals were gone, all the villagers we had at home and at the villages we've been at, every entity that we interacted with, every entity that shouldn't despawn just despawned, they're all gone. We do not have any backup from this world, and we are now afraid of starting another or keep going with this one for if the same issue would occur, and we only found old information and threads about this, nothing recent. We do not know what to do, how to play or what happened.
