Just started a new game to try out the new patch, and maaaaan Sloppy is rough. Adrienne apparently always has both Sloppy and Bratty, which makes her kind of a nightmare to deal with. Sloopy is a 15% chance to decrease discipline. All the ways to increase discipline (guard duty, stables, arena, academy, etc.) have a 15% or lower chance to proc, so unless you assign them to multiple sources, discipline gain will average out to zero.
You can reduce Sloppy by increasing perfectionist, but unless you start at character creation with the taskmaster trait, you're shit out of luck, because raising perfectionism requires 60 discipline. And the one source that COULD outpace the discipline loss, house maid with a maid dress and eventually the head maid title, straight up disables discipline gain.
So to actually get rid of Sloppy, you need to make them a liability in your tavern, keep them afraid, have them trained by a workaholic, and then reward their bad behavior by buying them a pony.
I'm mostly salty because Sloppy fucks up the one thing that Adrienne is supposed to be good at, which is accounting.
