2.2F Game crashing on Eleutheroi turn

My game crashes repeatedly on the AI Eleutheroi turn.
It happens on turn 921...I can't get past this turn due to this error.
Could someone please have a look at the attached log and help with this problem?

Nothing unusual in there; have you tried watching the AI turn?

I no longer have the campaign script for 2.2f, so I have no idea what it might be trying to do, or if it's something we fixed a long time ago.
