Hello,
I just found out that if one places blocks (I used half slabs on top of each other so it makes a "full" block, not sure if that will help.) under water and then tries to "swim" (More like floating) with their had above water while mining said block, doing some process of having you head above water, then below it quickly (not sure how I even did it, it just happened.) you can mine blocks under water as if you where above water. I have even stayed under water for 5+ seconds without mining anything and it still happened. Just wondering if anyone else has this bug.


Thanks for reading,

I had no gear on when I was doing it, so I don't think that would be it.

 

My head was below water, but the mining speed is the same as if I was above water.
