I have a problem playing this campaign. It's, probably, not a bug so I am posting it here. Very early in the game some factions are destroyed very quickly by some other factions after several turns. For example, Serbia is destroyed very fast by Hungary, Genoa or Milan are destroyed by each other or by HRE too fast etc. I think that's just too quickly and not very interesting for the gameplay. So, is there a solution to make those or any other factions live much longer (how to make them stronger)?
Cheers!
