Make Keg of Invisibility Potions. Take potion out of keg. Potion reads 'Night Sight' Still works like Invisibility. Not too big of a deal, unless you are trying to sell individual pots on a vendor. People think you are trying to scam them with NS pots instead of Invis. You would think QA would catch this when it was first introduced. Apparently not. Here we are 2 years later and its a problem.
