Senna's causing some pretty major crashes/freezes at the moment

I've played several matches since Senna came out, and a few of them at some point in the game just froze up completely and forced me to restart my PC. All the games that did crash though had Senna in them, so it's fair to assume that something about her is causing the game to crash. Anyone else having this problem? I'm hoping to give this some visibility so that it can be looked at and fixed.
