AEC Problem With Optional height and Weight Rules
The rule on page 151 don't allow currently for a character to be at just the base height or base weight.
So for example, no human female will never be 5'6", but will be taller or shorter if using the table and never have a weight of 130.
The dice roll to determine if the modifier is added or subtracted needs to have a result of no change to base that can be gotten.
