Illegal Stance

I was in my Minecraft world today and I entered a command something like this: /tp 0 10000000000000000 0. It was something like that. I was instantly kicked from my single-player world with the issue; Connection Lost: Illegal Stance..... and it puts me in the multiplayer screen (the list of my servers). Note that my game didn't crash it kicked me from my single-player world with the Issue above. My main concern for posting this is that, my world now does now not work, I think it is corrupt or something (don't quote me on this) If I try loading my single-player world, it simply doesn't let me in, and just says connection lost: illegal stance, and puts me on the Multiplayer Screen. I hope you fix this, it is my stupid fault for trying to do that command anyway... thanks. One last thing.. I was actually in 1.7.4 Sincerely, Chris
