[Dark Heresy 2nd Edition] Unnatural Characteristics not being added on successful tests

[asorel1942]

If a character sheet has a value in the "Unnatural Characteristic" box (e.g., SC below has a Strength of 25 and Unnatural Strength (1)), half of the Unnatural Characteristic value, rounded up, should be added to Degrees of Success on a success, but only on a success, per rule SC below. Currently, the sheet does not add Unnatural Characteristic values on a successful test.
