So I decided to play a norse dynasty called 'Gautske' in 867 start. The game went fine for awhile and before 1000 I managed to form the Kingdom of some random unpronounceable norse place name AKA Sweden, with 25 dukes and counts serving the King.
Before the Conclave I never patched the game beyond the SoA so I had no experience with the infamous 'Seduction' focus, and in my 5 previous post-Conclave games I had no adultery problem pehaps because I picked the 'Family' focus first. Now this time, about 3 or 4 dukes and counts in the Kingdom decided to go seduce spree and unfortunately my firstborn couldn't pick any focus, because he's unlanded.
Eventually his wife decided that some random 56 years old count of unpronounceable place is better than her ambitious, quick, diligent and 'Grey Eminence' husband, who happens to be the Crown Prince by the way. I picked the 'Intrigue' focus and had imprisoned the dude, but couldn't imprison nor assassinate the Crown Princess because her stats was so good.
At this point I had no idea how bad this thing could go, and I went to see what was going on by using in-game character finder. Turns out almost every adult woman had either 'Rejecting Seduction Attempts' trait or 'Lover's Pox'. The old man had 'Lover's Pox' as well. I suspect he was spreading it to these victims, and eventually to the Crown Princess.
Okay, so now I know that the Way of Life DLC is broken, even a year and half after its release, and that any sane, good man should not even buy this one, but I want to finish this run first. I think I'll just jail anyone who has picked up the 'Seduction' focus from this time on, however teh 'Lover's Pox' on the seduction victims remains a problem, even more so as I suspect this disease to be a STD. Is there any cure?
