[Gameplay] Draven Axes Dissapearing

When I throw my axe and the intended target becomes untargetable (e.g. minion dying or yi alpha strike), the axe does not bounce or cancel, it just disappears leaving me with 1 axe only. If i have only 1 axe when the bug occurs, it usually leaves the hand the axe was in empty (visually). to reproduce the bug:

1. start axes ( 1 or 2)
2. attack a target that becomes untargetable like maokai w or yi q (hard to do on purpose with the minions)

I will edit the post the next time it happens with as many screenshots as I can get.
