Its 183 BC, I am playing Parthia. The Saka I am pretty sure did nothing so far, they are just in their camped state and sitting there. They might do some diplomacy here and there but they haven't moved from Nisa in since forever.
EDIT:The Parthia campaign started having too many crashes, so I switched to Pergamum, its year 198BC , and I am besieging Ephesus, however when I end the turn and all the factions end their I get a CTD...
