I've actually experienced the aforementioned match crashes after patch 1.07--nearly every night (between 7 & 11, which are the suggested hours of play so perhaps heavy traffic could be related).The latest was last night, and I wrote down the code it gave me in case it might be of use: 18:3:1:0:0.
It always seems to happen during team play.
I'm not sure if it's because those tend to last longer so there's a higher probability of the issue occuring or what. Anyhow, I hope this helps narrow the problem. Feel free to ask if any further information is needed by the team.
