Reeds replace water.

Hello, I played in the single player game and I had a bug that the reed was not optical unit. That is, I put a reed in the water and the water is gone.

I thought the reed either just wouldn't fit or would break right away.

But when I put the reed in the water it just replaced the water block.

Steps to Reproduce:
Taking a reed in your hand
Put the reed in the block of water under which the ground is located.
Reeds replace water.
