Invalid Item monitors incorrectly spawn dust clouds when Fang's pop gun fails to hit

This only happens the first time it fails, but it feels like the game is taunting you for being juuuuust a little bit off of where you can hit the box. (This may also be a problem with the pop gun's vertical aiming?)

Not a bug, and not happening for the reasons you think it is. This is the Fang ghost replay having its "breaking the monitor" event being played back, which spawns an explosion where the object was destroyed to indicate it was successfully done in the replay. If you do the same thing in singleplayer, the explosion puff won't happen.
