For the last couple of weeks, when I edit a running docker I run the risk of the restart failing and then the docker image disappearing - even when I go to restore via CA the previous settings will be gone.  The docker will hang on restarting in the GUI and then eventually just disappear.  Stopping dockers also used to be a problem, but since I moved my docker image from a UD to my cache this seems to have gone away.   Edit: stopping dockers still a problem with image on cache - wheel
