I solved it with a gordian knot, i made a backup of "Session_13249614278988106"
before exit the session, then i moved out all 4 destroyed session files, and just copy pasted "Session_13249614278988106" to the folder and then lett "continue where you left of" pretend this was the current session
This sucks...that Opera only backup the current and previous session, we need autosaving addons, and i have ateast recieved several tips from internet
