2 Mains Draven Axes Bug

The first issue isn't really a bug but more like a bad coding of the axes, when you follow someone and you keep attacking moving to him then you hurt to any physic obstacle (minion, wall , champs, turret..) the axe will drop at the EXTREME opposite of where you actually clicked after the autos,

The second one is even worst because as you can clearly see the axe completely disappear after landing the auto, as a one trick draven I can tell you this happen 1 games on 3 at least and it can really ruin the game for you especially on a close play.

There is a last bug, when i bought a B.F sword with draven and ennemy bought ninja tabi my B.F sword got removed, is that intended ?
