Thunder-Bear i see what you mean by vassals getting around admin authority with the theme system. I was wondering why they could declare war. I might have to edit some CBs

Vassal raids could definitely be interesting.

My previous statement is in relation to the recent dlc, Roads to Power as even though the vassals can't declare war due to Admin authority they can get around that by the cb's offered to frontier and naval theme.

I had an idea to stop vassal expansion but still keeping with the frontier style. Instead of a CB for conquest how about the ability to raid instead? whether over land for frontier contract or by sea with the naval?
I believe this could be done by adjusting the vassal contract file. Thoughts?

I have not seen the mod but i could take a look at it. I also probably need to study on how to alter the code more in order to pull it off.

I have a suggestion.

Have you seen the Unjust Rulers mod?

My suggestion is take the mechanics of Unjust Rulers, flip it on it's head - and make "Ruler Strength/Legitimacy has impact!" Depending on how strong the ruler/centralism is, certain folks wouldn't expand their empires. Weak rulers, would have strong vassals who would and did ignore them throughout history. Wars started because of border disputes and territories changing hands more than once.

The mod is updated to 1.10 and above. It could work for 1.9 but i wouldn't know.

Can this mod be used in version 1.9 and a save game?

It does prevent it from what i can tell.

I assume this mod stops ai vassal declaring external wars. But I hope it doesn't prevent ai vassals declaring external wars if their ruler is an ai.

Thanks. I'm glad you like it.

Great MOD. Only makes sense, no vassal should wage war to take lands without you as a liege to give permission.

Understood, have a nice day.

im not sure my opinion on this

just what i was looking for
