Just another issue and more evidence of what a number of us have been discovering about the, let's call it Fuzzy Math, that appears to be implemented

Going over 100 in Enchantment (not sure how much over, might not be much), select an item, a gem (say Black Soul Gem for max power), select enchantment. Defaults to max damage, charges says 000. Start sliding the damage down, which should increase the charges, instead the charges
decrease. Definitely not working as intended.
