Patch 1.2.1 out now!
• Added an opinion bonus for vassals with a very low opinion towards the predecessor
• Added support for game version 1.3.0

Update 2 out now!

Vassals and other rulers will now react to the abdication of a ruler. The opinion penalty depends on the relationship with the abdicated ruler.

Update 1 out now!

Are you tired of your vassals always acting against your will? Or have you already negotiated future alliances with your vassals 20 years in advance, but you don't want to wait any longer? Then take your chance now!
With Update 1 you can force your vassals to give way to their heir.
