I guess the best way to find out who made the planning error would be for you to ask your Ops whether Astraeus Ops requested the change the night before (!).
Get your own ship in order before pointing fingers.
And Astraeus hasn't done any self-sponsored stuff for 2 years (since the management changes) so a good friend there tells me (that one actually upset my ex-colleague when I asked him!).
