Feat Powers with weapon prerequisites do not calculate attack/damage bonuses

[thoth-process]

If a Feat Power has a Requirement line such as "You must be wielding a gouge.", the power never provides attack/damage bonus calculations in the builder or on the Sheet, whether wielding the appropriate weapon or not. Removing this Requirements line displays the calculations properly, but does not restrict the weapon wielded. Changing it to a different weapon (even a core weapon like "Battleaxe") does not resolve the issue or display the calculations, so it's not a matter of gouge missing from the list.
