[Gameplay] 'Outsmited' by no smite

Just want to put this in as a problem because it literally just ended my last game due to whatever weird bug, but somehow despite having 680 damage on Smite and hitting Baron just below 680, enemy Sylas was able to still steal the Baron.

Clearly some bug, give me my points back, etc. I'm not some panic smiter. I play cool as a cucumber always and never miss a smite. Also, he was silenced.
