This water glitch that I will be talking about is different from some bugs.

This bug occurred when I was building something on a minecraft creative world, where when I place water on a half slab on the top half of a block, the water spawns inside the half slab as if it was transparent.

The next part of this bug occurred when i placed a half slab on the bottom half of a block and then when i clicked on one of the sides of the half slab to place water on the conjoining block, it spawned on top of the half slab.

Half-Slab Problem 1:
1. Place half-slab on top half of block.

2. Get water bucket.

3. Place water on top of half-slab, the water should spawn inside it.

Half Slab Problem 2:
1. Place half-slab on bottom half of block.

2. Get water bucket.

3. Place water on one of the half-slab sides showing, the water should spawn on top of the half slab.
