Count skills increased in dialog towards leveling
Some quests reward the player by increasing a certain skill by one point, in the dialog window. If this skill is a major or minor skill, it does not count toward the next level as it should.
The mod Less Generic NPCs uses this mechanic frequently, but I'm pretty sure it happens in the base game on a few occasions as well. Unfortunately I can't find any such quests at the moment.
