Same issue - so far, only tested playing any previously-saved deck during a challenge match with a friend. No matter who hosts, the submit error occurs. If I am not hosting, it loads the profile page and crashes on the host's side. If I host, shows the opponent the profile page and then gives me the deck validation error. No need to attach a log file since this issue is far more than a local problem on my machine.
