1. If I hit reset on a race's ability screen and then flick back to the first tab, sometimes all their abilities will still be listed and going back to the ability tab I find that my reset has been undone. Hitting reset and then selecting something and THEN changing back to the first tab resolves this problem.
2. I reset the Drath and changed to the first tab to see what their racial bonuses were. One was +25 Diplomacy. Changing to the abilities tab I then decided to give them additional diplomacy, except this didn't add to diplomacy, it erased the existing score and changed it to my setting, +10. Unchecking +10 simply removed all diplomacy bonuses, the +25 didn't come back until I reset them again.
