For clarification of the rules... for a simple crash where autosave interval = 1 or manual save within at least 1 turn is available, all you need to do is notify and continue -- repeating all moves as best you can before the crash. No need to wait for response from staff.
For other save-related issues (including crashes where the number of turns needin to be replayed is greater than 1) you should notify and await instructions and a stern scolding if you have failed to set your autosave interval to 1.
