I was exiting a cave that I do not remember but I do remember it was close to ancients acsent then I was thinking "why not exit the cave with whirlwind sprint and when I exited everything was super blurry and impossible to play, I heard of that bug before but I did not know that is how you cause the bug. I was just glad I entered the cave the second time, I went out in the world with the blurred vision. I was killed by a bear. The second time I went in the cave and then reexited.
