Not precisely an expert, but this aspect of the game seems to be handled in the file:
The fall of Vienna will give another 10, and the fall of Paris 20 for the CPs.
So Bucharest government only bets on winning horses
In this case you could add 5 (for example) after the fall of Hermannstadt and Klausenburg (most important cities in Hapsburg's Principality of Transylvania).
Historically after the dead of King Carol (Hohenzollern-Sigmaringen and pro CPs), Romania just waited for an opportunity to gain territory. Some options affecting one side and the other could be added.
The game is old, and we are in the happy world of modders, I am searching for one, but nobody volunteers
Just curiosity, is it a three humans game? The CPs seem to be in a very difficult situation.
