When playing with my family on our Realms world, we keep freezing (all while doing our own thing) and get disconnected, only to relog to find we lost anywhere from 15-30mins of work.  It makes us want to cancel our realms subscription.  Realms is so convenient for us, but this is making us not want to develop any further or even use the service.  Please help us Obi-Mo-jang... You're our only Hope!
