A decent amount of the good/bad modifiers are incorrectly placed (good labeled modifiers are actually bad and vice-versa). I've managed to find the following modifiers guilty of this:
1) Provincial --> Holding Construction Times (hovering over the "good" effect you find it actually increases the construction time instead of decreasing it)
- This is true for all other construction time modifiers EXCEPT Building Construction Time
2) Governing --> Short Reign Duration
3) Military --> Men-at-Arms Maintenance
4) Men-at-arms Maintenance per Dread
5) Army Gold Maintenance
6) Friendly Fatal Casualties
7) Siege Phase Time
8) Embarkation Cost
9) Hostile County Attrition
