Ooh - you are CLEVER!I deleted the entry because there was already an entry pertaining to ownership for Carthage - because Carthage starts owning one of the 4 regions by default. But I can't edit the integer there, so it crashes. If you are right, maybe I can just set both ownership entries to Carthage - so one entry will show Carthage owning 1, and the other entry will show Carthage owning the other 3. That would avoid having to edit the systembyte integer we can't currently edit. You have me excited. I will try it when I get home, unfortunately about 12 hours from now.That said, I still have no clue how faction_province_manager figures out which regions it's talking about. In the entry for carthage, there's an ownership entry for carthage with a byte[1] which obviously corresponds to the city of Carthage, and there's an ownership entry for Libya with a byte[3] which clearly corresponds to the 3 provinces Libya owns...but there's nothing to indicate how the game determines that the byte[1] is carthage in particular and the byte[3] is the other 3. There don't seem to be individual entries for each Libya region; it's just all done together. Which means that switching ownership is all or nothing - I couldn't, for example, switch it so that Carthage owned 3 out of the 4 but not all 4. More work will have to be done to figure out how the game designates what particular regions are owned by which faction, rather than just the ratio in the province as a whole. If that makes sense.
