So I wanted to test the Bad Luck effect so I found an underwater shipwreck and put night vision on. Then I found a chest that at certain angles turns translucent. The night vision ran off and it was still translucent.
It only seems to work in shipwreck in the chest room.
Here was the seed and cords that I found it on in my world
Cords: X=2354 Y=38 Z=-701
Also F3 seems to fix it
