[FIXED] /Challenge World Boundary Problem (I think)

[Vulkanyaz]

I am in /challenge and talking to somebody at the same time (Yes it is "extreme" multi-tasking!), so to stop the /challenge quickly to talk I use /kill.

I arrive at a spawnpoint, and then /visit to looks at people in jail while talking. 

But then I get pulled through the ground, all the way down through to the police carpark and fly towards the /challenge area while a "Stay within the world boundaries" message appears onscreen.
