I'm not sure exactly where to report an in-game typo, but the AA description for Group Perfected Invisibility and Group Perfected Invisibility To Undead both use the word 'than' when the word 'that' would be more appropriate. I don't know if this would make a difference, but this is for an enchanter's AA description.
