I've played a lot of Spelunky and for the most part I love it but when playing co-op I've come across this weird glitch. After my co-op partner is freed from their coffin instead of them coming out of it I do. Not only that but I don't have any of my items afterwards. Its happened about three or four times. It usually only happens later in the game, around the temple/city of gold levels. I have some videos of the glitch in some of my "lets play" series.

I was wondering if anyone else has come across this glitch?
