Hmm, i was thinking that such a pop up would say "Connection to PBW server lost. Your game turn has been saved as file XXXX in your \Savegame directory" or the like, not far off what you already said

Then once connection to PBW can be reestablished (even if RTC is exited then restarted at another time when a PBW connection can be made) and you select the specific game that had already saved that you had already played that game turn for, it would ask if you would like to send the game turn that you already made or delete it and replay the turn
