Game crashes every time Gromp is revealed.

As the title says, just played a game where every time myself or a teammate revealed the Gromp my game would bug splat and give me an error report suggesting I reinstall League. In the message (didn't notice this at first) it said something about SRU_Gromp. I should have screen shot the actual message, but didn't think about it.

So we lost that game, I'm sure my teammates were less than thrilled that their support kept disconnecting, but there wasn't anything I could do. Asked them not to go by gromp, chose not to believe me, whatever. Lost the game and decided to test it in a custom to see if I could reproduce the results. Went to gromp, the second it spawned my game crashed again.

Currently reinstalling LoL, I'm assuming it was just something that didn't get installed correctly in the patch, so hopefully a fresh install will fix it. I'll keep you updated on here, but also was curious if anyone else had ever run into this issue, and if so, how they fixed it.

Edit: Forgot to mention. The game I played right before this one was a jungle game and never had this issue in that game. The jungle game was on Red side, both the support game and my custom were on Blue side. Not sure if that matters at all.
