I had the same problem with my game in french language set up. As a result i got two defeats in a row and got 0 victories in a sealed pack Event. I tried a new one and immediately got one defeat due to game crashing. It is then that i read this post and learned that i was not the only one with this problem and that there were no more bug in english. I think this is true as i put the game in english and then managed 6 victories without me or the opponent crashing in the event. I saw some similar coment.
