Working as Designed Mace glitch

[Freyon77]

When you stay in 2x2 block square your mace can go invisible and go through 1 block.
To reproduce stay in 2x2 square use mace in one direction to the wall in front of your face and the mace will jump to another side through blocks. Allowing you to unlimited afk farm without taking single damage.

There are plenty weapons which can fire through solid blocks, as well as ways to make solid blocks let projectiles through one-way, so this is intentional.

Thanks for the report! Because this happens on the PC version, this is currently working as intended.
