Draven Spinning Axe Doesn't Bounce Back 2 times in a row

Hey Riot, This Bug has been happening more often lately, and I'm wondering if you guys could take a look at it. I wasn't going to report it but then I saw it happen multiple times to myself, and to other people as well. In the video linked (at 11:41) you can see after Draven gets a kill, he attacks a minion and his axe does not come back, then he queues up another axe and attacks a ward, and it too just disappears. Any fix on this bug would be great!
