Certain chunk in world causes game to crash

Hi, 

I started up a new world with mates and the world was working fine. Then I bulit a super smelter on survival that has a lot of piston movement. Nothing happened for a couple of hours until I went into a nether portal. The game then froze and when i restarted the game and tired to load the world again it crashed. Eventually after turning settings down such as simulation chunk distance. The world loaded back up. I went back through the portal and went to the smelter. As I approached it the game froze, unfroze and then it shut down the game. I have attempted to copy the world in creative mode, making no difference and can't find any possible fixes online. No matter what direction I enter the chunk it crashes.
