Stainless steel mod medieval 2 crash after 1 turn

Total war games sometimes have Moments of Awesome. Nothing beats the thrill of a well-fought battle.

There is currently the fifth siege of Mediolanum going on and I'm trying to bribe the Sweboz and Carthago into attacking Gaul. Now, just as Macedon prepares to attack me in the Balkans, the Aedui are crossing the alps again, and the Averni are nowhere to be seen. When I last checked the map, the Aedui were down to maybe two provinces in Gaul.

To make matters perfect: I allied with the Averni and beat the Aedui out of Italy. Plus, I lost something like 80% of one army trying to take the Epeirote capital in a quick siege. I'm lucky the computer never, ever thinks about covering their flanks. The only way I've found to deal with elite phalanges was by throwing about three times their number of principes at their front and then throw a sizeable amount of heavy cavalry into their rear. When I finally went to attack Epeiros, they, of course, immediately allied with Makedon and the Koinon Hellenon and utterly crushed my first assault. Easy since phalanxes are overpowered against anything but skirmish cavalry, but taking anything east of Turkey was painful. I loved Rome, and finished the entire campaign as Macedonia. The HRE don't quite have the military might to face me at the moment in any real fashion. I was switching the two brothers so that the whiny one would either start feeling appreciated fighting the HRE or die in the attempt. Both are currently in mainland Europe now: one is currently fighting the Holy Roman Empire who, most unwisely, declared war on me over a city on the Northern coast of France/Germany that I can't remember the name of while the other is pissing and moaning about having to sit on a peaceful border with France (and losing loyalty at a rate that's quite astounding, actually.) The new Scottish king ruled a united England until dying in bed, leaving two sons. I'd just finished conquering the English territories as Scotland, shattering the English king's army at Nottingham thanks to help from the French in mainland Europe.

Heh, even though I stopped playing my second playthrough of Medieval 2 quite some time ago (close to a year and a half now), I still remember the situation.
