Im having this issue that IA kingdoms after never go down 600k bank and 200k sum of all vassals. Could be some vainilla protection so they dont go debt and lose?
For example last wars with blandia and norten they both get around 3 millions and they had just that around 600k bank and 600k all vassals gold, yet the only that changed is that vasalls gold went to 200k, the problem its anfter peace time the get to 600k again and make same ofensives makeing it boring to deal with the same over and over.
