YEah, that would figure. From memory I think I've had the same occur to me too.

For the combat traits it's relatively easy to confirm as from the triggers the awarding of the traits can be tracked easily, e.g. 1 Chance 100 is a 100% that 1 point will be awarded. For the traits with lower chances (%) of being awarded, things are much more difficult to track. Although jumping the first two levels of any trait (assuming thresholds go up 1, 2, 4, 8) should be easy enough to spot for a naive general (i.e. level 0).
