Zyra changes broke snare consistency

During a single recent game as Zyra (since the changes), I noticed at least 3 instances of a snare going straight through someone and not snaring them. My ping during that game was about 45, so it's highly unlikely that lag was to blame (the collision detection code seems to be failing here, and I'm not sure if that's due to issues introduced in the 6.9 patch or not)...
