Sometimes, when I target a specific minion with Syndra's Force of Will and this minion is out of range, after Syndra walks nearer to it she actually grabs another minion nearby. This bug is especially noticeable when trying to grab the cannon minion.

To Reproduce
Press W and click on a specific minion which is out of the spell range (or if using smartcast hold your mouse over the minion so you see the red border indicating that you target this minion, and then press W)

I'm sure I did not missclick. I explicitly click on a minion but another one is grabbed. This seems to happen likely if the minions are clobbed together in a wave.

Not sure if this also happens on minions which are in range.

Anyway this ability is still in infancy, it generally seems buggy and kinda unresponsive.
