Neatness ability is not increasing maximum mana

[falchur]

I have 2 levels in the Neatness ability and have destroyed a lot of items and all I got are crystals, nevertheless, the ability description indicates that the first level of ability should also increase the maximum mana by +2 and the second level of ability should increase the maximum mana by +4 upon successful destruction of a magical item. I am a mage and one of the main reasons I wanted this ability is to increase my maximum damage to blast my enemies to ashes, and now I am really dissapointed. I wonder if the problem is a bug in the program.
