My lords keep on getting vices which reduce farm and trade income by 10%. I try stripping them all of their titles when they get these vices and sometimes these vices dissapear, but usually they stay and a lot of lvl 9 acumen generals and great builders have been renderred redundant because of this. I heard somewhere here that if you put your tax to normal then none of your lords get these vices, but after a few turns of doing this they are still getting vices. Is there anyway to stop them getting these vices? It seems loads of my lords get these vices if I lose a province and some of my lords which have been ruling the same province for decades don't get any of these vices. Also it seems emmisaries have an effect in stopping lords from becomming corrupt.
