Hmm...no I haven't had connection errors but lots of times my game just crashes without the message.

It has gotten pretty bad for me again. I have not been able to play during this event, because I get disconnected from the network the moment that I try to go to the stage select page... I have tried on different networks, and at different times of the day...

I wonder if there is a different reason for this? I remember early on that there was an issue with the Friend List that caused similar issues...
