Spheres pushed away by 
's E (Scatter the Weak) are being stopped by 
's E (Event Horizon).
Youtube video representing the issue.
This seems to be the case because of the newly added ability of Event Horizon to stop dashes. My guess is that since everything is, of course, coded as minions, Syndra's spheres count as dashing minions and Veigar's E stops any dashing unit. And that doesn't seem right, does it.
Assuming you're not crazy and it's actually happening as you describe... yeah, I'd believe thats a bug that should be addressed.
Add some screenshot / video to support the evidence. It'll help reds to flag it out more quickly
Added a video.
Not intended surely, but that's actually fucking hilarious.
Well yeah, they're coded as minions. ;)
That's pretty cool to be honest.
Honestly, I think that should stay.
Veigar needs all the help he can get.
Make this a feature and have his cage stop projectiles.
Yes I know, I hate Yasuo's Wind Wall too, but damnit, give our Tiny Master of Evil SOMETHING.
I play Syndra, I don't play Veigar. I'm still ok with this, I think even though it's most likely unintended, it's actually really cool.
Well I mean the balls are dashing, so it makes sense that they would be stopped.
probably the same thing with like 
E
That's pretty awesome for Veigar I guess, but just really funny either way.
