For about three weeks now, while playing Historic Brawl, my game has crashed if it goes past a certain length of time. I have played other formats such as Timeless Best of One and Jump In events, and no matter the length of time, the client doesn't crash. For some reason, while playing Historic Brawl, it crashes all the time. I haven't timed it yet, but I would say around 8 to 10 minutes, my game will crash/close out. Every time I try to go back in, it will attempt to put me back in the game and then just repeatedly close out. Eventually, after a while, I get back in and I'm back on the Arena home screen. A very irritating bug, as Historic Brawl is my favorite on Arena.
