It seems like the server cached my request for rollback, didn't show any sign its rolling back and then all of a sudden rolled three turns back.
I'm really sorry for this
I will PM llama and ask if its possible to set game back to turn 64. Please do not delete the "Victoria: Rolled back to turn 64" emails you got as you would need those turns in case the server is set back to turn 64.
I will keep you posted and hope this unfortunate affair is resolved quickly.
