Hi my minecraft world crashes when i launch, it happend while i reached a certain point where it hadn't loaded. I suspect the world was trying to generate something, that caused the bug, seeing how my friend crashed and could not join again after reaching a certain point of the map and when i reached the same place as he crashed I could not open the server again.
