After leaving the axe on the ground, if you press again down special and Ragnir gets a hit before the axe reaches him, the axe will fly to the end of the map but the main problem comes out when you put another axe in the stage and try to press again down special...the axe get stuck in the same spot while rotating and keeping on the hitbox until Ragnir gets hit again, freezing in the ground, without an hitbox but occupying a certain part of the screen.
it is possible to repeat this bug forever until the "soil" is completely covered by freezed axes.

About a possible solution.. (every time the player press down special to "attract" the axe, instead of using ragnir as target to reach, why don't use a point, a second object without an hitbox otherwise, which is spawned when a player uses down special and despawn when the axe reaches it, while not having an actual hitbox can ensure that the enemies can never interfere with it).

I'm not a programmer so i can't see if there could be any problems with this idea.

If i have not been clear, i'll try to be more explanatory.
