Placing brick bug

On the first screen I am on top of stairs I’ve just built. As you can see you have access to top floor.

Next one - I’m downstairs trying to finish a wall. I’m using bottom of a step block to place a block of rock.

After an attempt. You can see the block is not where it should be, if you look closer you should see it landed on top of the step.

Here seen clearly on top of stairs after I came back to the spot you’ve seen on the first screenshot.

I’ve noticed It was reported before, as far as end of 2015, but decided to post this anyway since it’s been so long time since and maybe its worth mentioning again.

Do you have a link to the 2015 post for reference?

It popped up when I was writing a post. Will try to get it when I’m back from work.

here it is
