Upon the MH3 my client (Windows PC) is crashing whenever the reward overlay comes up and/or upon completion of a match (i.e. any time i gain gold or experience; which triggers after every game, but also when I went to collect my 3 booster packs from MH3 launching). It hasn't affected gameplay, but it is very frustrating having to relaunch the client after every game.

To replicate I can play any game (thus far I have only played Draft games though) and it will crash upon completion of the game. It has happened after both wins and losses and upon trying to click the 'Claim' button for the 3 MH3 booster packs from my news item.
