I was exploring then crashed after loading a chunk and tried restarting the world but every time I load in it starts constructing the world and I log on for a few seconds before the world crashes. I tried disabling fast craft as its the suspected mod but it still has the same crash problem but then it says unknown problem mod. I also opened a new world with the same seed and went to the same coords but the new world didn't crash when I went there.
