Sion Q and E both still bugged

Sion still has two fairly major bugs with his skills, and a new one was just introduced:

Q: After Sion casts Q, he will shortly thereafter stop attacking. This is devastating. Example: I'm trying to burn a tower down as fast as I can, and I have a sheen item. So I cycle my abilities to proc sheen as much as possible. After cycling Q, within the next 1-2 seconds (not immediately), sion will interrupt his current attack and stop attacking until ordered to do so again. This happens no matter what he is attacking. Sion will always stop attacking some time after using Q

E: It still sometimes fails to push projectile minions/monsters through targets. https://youtu.be/mcPb22G1y_Y

E: new bug: Sion can shove rift Herald with E. While it is certainly hilarious, it is really unhelpful
