I have been making a map on 13w38a when I update to 13w38b and I look down roughly as soon as it hits -174 my game crashes. I have not used any mods but I have used MC edit so I can't automatically send bug reports

I tried with a different world that i had from 13w38a and it was fine? Here is the crash error anyway. Hope this gets fixed.

In 13w38c this is fixed.
