Arena freeze and then game crashes

Arena freezing issue is killing this game!
Who is going to pay back for all the lost gauntlets?  
To add insult to injury, every time it freezes I also lose the tournament and get reset back to square one in my progress.  It doesn’t even make sense that I would have lost, there was only 20-25 seconds left and I had 2.5 million to my opponent’s 850,000. Please fix the arena it is one of the best parts of the game and so many of us are having a problem with it!
