Loyal Vassals
This is a quick mod that makes it so when a vassal, puppet state, tributary, or satrapy does not join a war, the treaty doesn’t break and no war is declared. If a master or protector fails to join a vassal’s war then the treaty will be broken as normal.
I recommend putting it at the bottom of your mod load order to avoid conflicts.
