Easy to reproduce:
- Go to https://realtime-cube.appspot.com
- start a new game
- Open a second tab with the same game
- Make sure that both tabs are realtime connected upon change.
- Now, put your computer (in my case Mac OSX) in a sleep mode for 4 seconds (in my case just close it and re-open it).
- Go back to the game tabs and make a change
- The tabs are not sync with each other. All changes are not saved in document.
- Errors are not thrown during a save operation.
Any explanation? Should I reload the document at this point? How should I catch this situation?
