I'm guessing its something in my world in a certain chunk. It doesn't crash when playing other worlds and it hasn't crashed when I'm far away from the area. It crashes when I'm near the cow farm. I'd say probably with in 50 blocks it has a chance of crashing the game. Some times it won't even load the map.

Here is a zip file of the map. https://www.dropbox.com/s/2lzfe3xefpgacfe/Crash.zip?dl=0
