The funniest moment i recall, because there are been many, was when the Automatic Allegiance Fix entered in effect, it kicked every noble who was unaligned, including the rulers and council.
As far i remember only Sordnaz and Andrew remained in power that time (Dictatorship privileges) those kicked had to re-join their realms and of course, wait couple of days because new nobles couldn't be appointed to things.
Such good times!
