Well, this is the host save of a game that crashed on me in november of that year. When I ran the autosave in SP (the one I gave you here) it CTDed on jan 2. I think it has to do with the Russia AI giving her navy the same illegal movement as the retreat from pirates would cause in the seazones, since if you remove the Russian navies from the bugged seazones (1440 and 1585) the game runs fine for any country...
So yes, if humans would play it, there would be no problem (hence us in multiplayer continuing till november of that year).
So, that's the solution to the jan 3 crash. I don't know why the host save crashed for me in november, but that might be coincidence.
So, all in all I think, these problems all orginate from the map being bugged at these locations
