Thanks for your thoughts, folks. I find it really irritating when I'm trying to have a peaceful, economically productive spell for my princes to get lazy just coz there's no war on!

Drinkers really bug me (like my heir apparent, drat!), especially when I have a Muslim faction I thought once that might come from staying in provinces with taverns too long, but I doubt it now....

I suppose there's not a lot you can do about the random vices, but it would be nice to avoid the ones you can.
