Mine worked fine you just couldn't follow a player twice without it walking back to your point of origin.
No, it was so much worse than that. It would stay like 2+ blocks away at all times, sometimes walking backwards instead of forwards when they took a step, etc. And sometimes if you followed them for long enough (which was funny to watch), if they logged off you wouldn't be able to walk on your own at all either. You didn't lag out you just couldn't walk, lol. If you look back in this thread you'll see one of the early testers comment on the bad following
Speaking of it though, can I ask how mob size works?
For example, if I spawn a KBD who has size 3 or 5 or whatever at 3000, 3000; the yellow dot that appears on the minimap isnt
the actual NPC's coords, right? It's x + size/2 and y + size/2 or something?
So to get the 'area' a mob occupies, it would just be [position.x, position.y, position.x + size-1, position.y + size-1]?
