The Creation Kit wiki says:
"Ability: An Ability Perk Entry adds the selected Ability or Spell to the player when they acquire the perk."
Now, lets say my mod is added to an existing character who already has that perk I modified. So the perk is not effectively being acquired by the player, just being changed during the character load.
My question is: Will the game understand the perk now has an attached ability and add that ability to the player correctly?
