AI City Rebellion CTD

Hello,
my Parthian campaign is currently stopped by a CTD during the Romani AI turn. When I had the first problem of this kind, 10 game years earlier, I checked this forum and found the tip to find the rebellious city and stop it from rebelling. So I turned Syracouse into a ghost town via add_population.
Now the Romani are unable to control their cities again, not just one but 3 of them this time. Two of them I got over 80% loyality with my depopulation, but the remaining 17 inhabitants of Lilibeo wont move beyond 65%. Is my campaign lost or are there other ways to stop them from rebelling?

There are some tips for it here.

If nothing in the sticky helps, can I have a look at the save? I might be able to stop it rebelling.

Thanks for the offer, but after some trying I was able to move a Roman FM and his army from Gaul to Sicily. That seems to have stopped the rebellion. Thanks for the quick help.
