What's up, RMers?

Those steps should be followed for certain, but I know it makes no sense to think that my script is causing that issue. Especially when the code doesn't alter the item consumption feature while using the direct or check system.

KIND OF IMPORTANT EDIT

Just in case Wulfo's recommendation fails, and there is any possibility that KEquipSkills XP could be kind of permissive at the time that it performs the corresponding direct or check tasks, try this piece of code as a separate script.

Code:

class Game_Party
  def teach_item_skills?(item_id)
    return if item_number(item_id) == 0
    @actors.find {|actor| actor.teach_item_skills?(item_id) }
  end
end

It's a slightly modified version of the same method already present in the main KEquipSkills script because it only adds this line of code:

Code:

return if item_number(item_id) == 0

SUGGESTION

You could also discard any external influence following a modified version of Wulfo's debugging methodology. Instead of starting eliminating scripts and all that stuff, you pick a copy of my demo, with default scripts untouched plus 2 KEquipSkills scripts plus Game INI Data Extractor and start adding your custom scripts one by one.
