I was just trying to build a peninsula out into the water and noticed at a certain point no matter how much stone I lay down the height is 1 block lower than the rest... and it pisses me off... because I didn't know that was a thing and I've already started construction there and now I am annoyingly constrained because of SI problems counting pieces from the ground. Just frustrating is all... I wish the SI system worked a bit differently so that such a minor difference wasn't the end of the world.
