Hitboxes backwards on custom block model in 1.16.5

My custom block has its hitbox facing the opposite direction from where it is placed, while the model itself faces towards the player, the hitbox faces away from the player.

    Because towards North is -z, so the origin in on upper left corner.

    Easy way is just flip the direction in getShape, or just swap them manually.
