Description: item use with right click uses a block from inventory but retrieving block after placement disappears.
Tools: hammer and any other block (unconfirmed all blocks)

How: with the hammer on the hot bar and another block on the right next to it, make sure selector is on the hammer. right click and it places the adjacent block on the hot bar on the ground. picking up the placed black then destroys the block without replacement (such as a marble brick block or jack-o-lantern.

having nothing in the hotbar on the right did nothing.

*upon rechecking after moving around and more building. this seemed to be working normally but i was able to repeat it at the time and loss a few blocks prompting this post. something to watch out for and it seemed to be only 'blocks', not signs etc.
