I've been wondering this for some time, because I think that the host of my multiplayer game might be adding monarch points for himself when the game is not online. So can I find out about this somewhere in the save file?
Oh and the reason why I think this is, is because previously the game notified me when i changed nation in the "lobby", like: "This savegame is meant to be played as England..." etc. but now it says nothing, and my friends technology has improved dramatically, while he has also got tons of admin ideas and cores.
At the end of a game session, save the game locally and store it somewhere.
When you rejoin the game later, grab the new save that you get sent.
Use a diff tool to see what's different.
