I'm just testing things in creative with the attunement altar, and I got close to pick up a crystal that just finished attuning, and the altar sucked me in. I was crouching when I went in close to pick it up in hopes that it wouldn't suck me in, just because I didn't need to sit through the whole animation when I'm not testing player attunement.

So it'd be nice if by crouch walking, the attunement altar wouldn't suck me in while it's active.
