2 game-breaking Syndra bugs

I'm having 2 problems with Syndra recently. Really, 3.

1. Sometimes, when launching a stun, the ball will either move and not stun the player (it appears to go right through them) OR (#3?) the ball will not move at all, and not do anything even though you clearly e'd it. This happens only if qe is executed before the q animation completes, I've noticed.
2. Syndra w, upon grabbing either a ball or minion, if instantly throwing it may get caught on walls (for me it happens at dragon entrance a lot) and will go nowhere, remaining attached to Syndra via the visible link but actually did no damage and did not go where you aimed it, it simply zooms in the air then back down again as if it was not recasted and you just walk around with the minion again then it disappears altogether. this appears to be a legit animation, but i can't think of a reason how i am causing it.

These 2 bugs are infuriating and have resulted in my death many times last game so I hope someone is on this. It simply puts your abilities on cool down, making you half worthless. I have not had them happen back to back though.
