is there tech support here?
I'm really sorry to hear you've lost your work. Unfortunately, if you were disconnected from our server, we cannot restore your work. Disconnection means the data never reached our server.
I'm sorry to bring you this bad news!
The data was there. Then there was auto reboot in the process of my action. After that, the data is gone. Do you have some autosave? Can you restore the state of the sheme to 4 hours ago?
