Do you have a recording of it? A few people now have said that they had the same thing happen yet but no one has posted a link to it. I'm interested to see what similarities there were between the two situations. Might be able to better determine what caused this in that case

I think I have it recorded on my Xbox. I'll have to link it when I get home from work.

If you go on xboxclips.com you can type in your GT and link it from there
