We noticed that in our latest game, my wife had six attribute points to spend at character creation instead of three. I retraced her steps and figured out that it was because she had finished creating her character, changed her mind and dropped from the game (pushing A to edit does nothing). She then rejoined using the same profile, and the game reallocates the stat points a second time, giving her six instead of three.
You can do this endlessly.
Changing class/race or profiles resets everything, so I don't think it's a major problem, but thought I would point it out anyways.
