Slow post game lobby regroup

After a game players will be unable to hear each other and stuck on the post game carnage report. Sometimes we get back into the lobby, other times the game crashes. Please advise.

The carnage report needs to be last on the list of stability. Get players into the lobby again and then bring up the carnage report. People are backing out of lobbies because they have no idea that pressing a button can boot them right out.
