As I do not have BI with the mini-mod installed (btw:which pack are you talking about?), I would ask to give some more information about the crash itself, maybe you want to see the section in the Frequently encountered issues about CTD's.
I am pretty sure it is because Im letting Syracuse rebel :
Spoiler Alert, click show to read:
Use toggle_fow to check all settlements on the map for rebellion (meaning about to rebel, not being eleutheroi!) and prevent them from doing so.
Check for the pitchfork icon when double-clicking each city.
For each city with a pitchfork, make sure it does not rebel. There are many ways to do this:
EITHER: Reduce the population of all rebellious settlements: add_population <settlement> -4000, where settlement is the name of the settlement.
OR: Install the force diplomacy mod and force them to sell you the settlement.
OR: Teleport over a unit and lay siege to the settlement. move_character "<character name>" <x>, <y>. The character name is complicated
If he's named Appivs Cornelivs Blasio, for instance, his real name could be "AppivsG Romanvs", "AppivsJ Romanvs" or any other letter between A and K after his first name.
for Romans, and "Firstname Middlenamelastname" for others (make note of capitalization, hyphens and lacking space!). X and Y are the map coordinates to teleport him to.
You may get the coordinates where you want to go to by: Write show_cursorstat in the console (don't press enter), then point the mouse where you want to go and press enter to apply the command. The console will output the coordinates.
You cannot teleport to sea, cities or impassable terrain.
Do you want it to rebel (roleplay?), if not, I would start with decreasing the population if it is a AI-town (add_population CITYNAME -4000; until it drops down to 400), and building some law improvements (queue the buildings, then enter process_cq CITYNAME; add_money if you need some cash to do it) if it is your own town.
And yes, I do want it to rebel for roleplaying reasons. I am on the eve of the 2nd Punic War era so I thought that I would have a rebel Syracuse and a Carthaginian Lilibeo but it hasn't been working as of yet. I just moved some troops to Syracuse as it has many law buildings already.
wow man, that really helped! I was at 237BC and when ending the turn (Athenai and Chalkis were about to rebel, but i didn't care before i've written this article) the rometw.exe had got to stop or smthn like that. that was an annoying and also interesting problem to solve thanks!!! maybe in the name of many others as well
take care
