For the past couple days my Minecraft world hasn't been loading chunks properly. I'm playing on 1.17,1, and whenever I switch dimensions such as the end or the nether, only the chunk I'm in loads. The rest is void. When I try to step into the other unloaded chunks, I glitch and am not able to move. I've been playing on Java for a couple months now, and this just began 4 days ago. (1)

I noticed that my cat (tamed animals) hasn't been following me. Usually, when you tame a cat, it is supposed to follow you around. But recently, any animal I tame just sticks next to a block and doesnt follow me around sometimes...this results in me losing my Minecraft cat alot. I don't know if they get stuck in the block, but I have to move them far away to a flat empty surface for them to gain their ability to follow me around again. This happens very often, and began quite awhile ago. (2)
