Hi there, I'm new to the game, been playing for a couple of weeks now! I've noticed in one of my worlds though that suddenly I'm 200,000 blocks away from spawn? Obviously I started the world at 0,0 and my base was somewhere around -300 -60 but now its 211931 -64? I can work around it and still play the game fine, I just wanted to share a possible bug I've run into. It's happened in two of my worlds now, very strange
