Last evening I tried Bithynia for the first time. At the first turn I have besieged rebel town just east from me on the Black Sea. Next turn diplomatic information came that we signed a ceasefire ( I thought ceasefire with rebels is not possible..as your diplomat can not make it, just bribe them). So, in order to investigate if it is scripted somehow for the first turn, or if it is bug, I started campaign again. Recruited full roster of some cheaper troops at first turn and waited next few turns to see what will happen. Now, I remained in the war with rebels, but no matter I had only one province, and full stack army, my treasury went from starting 5 k (H/M) to more than 70 k in few turns. Now..this must be scripted, right? To put player out of the dept or something? While playing Europa Barbarorum, it was big and unrealistic problem, as you know, that you are in terrible debt if starting as small nation, but latter on, as you have bigger empire and take care about your development a bit you are floating in millions, and by mid game it becomes unrealistically easy.
But as much as EB thing was unrealistic, this RS script is also bit too much if is true. Having one province and full stack army and sitting there doing nothing for few turns, I guess you should not get 70 k?
And one more question...having trading rights do not increase your trade with that faction as far as I can see in trading summary...it is basically just for improving your diplomatic relations, right?
PS. one more economy question - how many free upkeep units you get if they are in garrison?
