I was just in my normal super flat creative mode world, messing with high regeneration levels in the void when I decided to teleport myself really low into it. This was when the chaos ensued. I did something like /tp @p ~ ~-100000000000000 ~ while falling through it, and the world closed saying "Invalid Player Movement". An "oh no" fell into my soul. I knew it was because of some integer overflow error, Minecraft has trouble handling universe size numbers. When I enter my world again, the game immediately crashes as soon as it loads. I go back into Minecraft and make a (too late now, but still) backup of the world. When I enter it again, the game can't even finish loading my world before the crash.
This is kind of a pressing bug, as anyone with any command knowledge knows how to use the /tp command, and any idiot like me or trolly younger sibling could use this to lock someone out of their world without immense otherwise effort.
Would love to see a fix for this, or at least an alternate method of dealing with this situation than an infinicrash.
