Gah. In my tests, the game CTD's during or following the Getai turn, and they DO have a city with high unrest (Gelonus - in fact it's empty!) So, sadly, it looks like one more instance of the now-fixed rebel city bug. Can somebody else download this file and confirm?

FWIW, I'm also seeing "Baktrian Belgium" on the strat map, so there may be map.rwm issues here as well.
