Multiplayer crashes

When I am playing multiplayer over local WiFi the game randomly crashes. Sometimes it freezes and asks if I want to close the app, wait, or report. Other times it just closes out the app. Happens with Nexus 7 connecting to a Kindle Fire HD server and vice versa. I know this is not from throwing eggs or snowballs because that is banned on the server and I am sitting right next to the person I am playing against.

I cannot reproduce as I do not know the cause of the crashes but it does happen multiple times during every multiplayer session.
