After updating to 1.17.30, I've had some incredible issues. Im playing in a 5 year old world, and last night the villagers that I've bred kept clipping through walls when they would wake up, choosing someone else's bed, and taking someone else's work station. I spent hours reseting their beds and work stations, only for them to choose another again. I even tried putting fences up around them, but they'd still no clip through them.

It gets worse. Today, when I loaded up my game, EVERY mob that I had is gone. My villagers, my cats, my dog, my horses and cows and sheep, my bees, my two golems, and even randomly, my two rowboats... it's like they all got Thanos Snapped. I got on the Minecraft Discord and it looks like people are having the same issue! Things are just vanishing suddenly for everyone. From mobs to armor mounts to blocks.
