So, I created a new world to test out my chain crafter data pack, and the world was fine, and I left.
But then when I spawned back in, some chunks were out of place, just standing there.
I don't know if I have a few mods installed, I don't think so, because it never happened before, but I dunno, what do you think?
Look at the above screenshot, that is not normal, right? There are a few more, but I only can send 1 screenshot. And besides, that wasn't there before.
